FlexSim 25.2.0 includes upgraded third-party licensing libraries which require an updated set of license server files based on Flexnet Publisher version 11.19.8.0 or higher. For background, see Version Compatibility Between Components. In terms of that article, the client library linked to the FlexEnabled application (FlexSim) was upgraded, so all the licensing components further up the list also require an upgrade. Thus, FlexSim has a new set of license server files available. Download the new license server files here:   https://flexs.im/lmtools-download   Suggested instructions:   1. Extract the new download and extract to a location right next to your previous license server tools, like in this screenshot:     2. Install the latest anchor service: Browse in the files to find flexsimserveractutil.exe. Right click and choose Run as Administrator. Go to Tools > Licensing Service > Install Anchor Service. For more information, see License Server - FlexNet Licensing Service 64.   3. Start the new lmtools.exe from the new folder. Your FlexSim_License service should be listed there.   4. Update the paths for lmgrd.exe, flexsim.lic, and log.log to point to the new files in the newly extracted folder.     5. After editing the three paths, save the service (button in upper right).   6. Check the service using Windows Services. Make sure that the "log on" tab is still set to use a "local system account".   7. Make sure the new lmgrd.exe and new flexsim.exe are allowed through the firewall. See lmtools - Add Windows Firewall exceptions.   8. Restart the service, either from the Start/Stop/Reread tab of lmtools or from Windows Services.   9. After you confirm everything is working properly, feel free to delete the folder of old FlexSim license server files.   If you run into any troubles, try stopping your existing FlexSim_License service first, then repeat the above steps.  

This model shows a simple way of bringing together all the separate picks in an order to be consolidated in a putwall. It also shows a great way of tracking flowitems while on a conveyor through the use of tracked variable labels. A side concept is that the order reserves a slot in a rack for all of the picks. Conveyor-Routing-Order-Consolidation.fsm

You should have already completed all preceding steps found in the article Hosting your FlexSim licenses with lmtools, including all those under the headings "Preparation and Prerequisites" and "Activate licenses to your license server". Your license server will communicate with client PCs using two executables, the lmgrd.exe licensing service and the flexsim.exe vendor daemon.   This article shows how to add exceptions for these applications through Windows Firewall. If you have additional firewalls or network appliances that need to be configured, please check the section Port Considerations at the end of this article.   Allow an app through Windows Firewall Port Considerations   Allow an app through Windows Firewall   Windows Firewall allows you to specify certain applications that will be allowed through different network types. If you're not sure about firewalls and networking, be sure to contact someone in your organization that administers these things.   You will need administrator privileges on your license server to add firewall exceptions.   Open the Allowed apps interface   Click the Start button or press the Windows key, then type Firewall into the search box. Choose the option to Allow an app through Windows Firewall.     If you don't see that option, you can choose the option Windows Defender Firewall at the top of the search results. This will open the Windows Defender Firewall topic the Control Panel. There you can choose Allow an app or feature through Windows Defender Firewall in the side panel:     Add a firewall exception for lmgrd.exe   In the Allowed apps window, click the Change Settings button, then the Allow another app… button.     In the Add an app window that opens, click the Browse… button. Navigate to extracted license server downloads. Double click lmgrd.exe to choose the file.     Click the Network types… button.   Check the boxes for the various network types that the firewall should allow. We recommend allowing your FlexNet licensing to communicate across all network types, but contact your server or network administrators if you're not sure.     Click Okay to close the Choose Network Types window.   Back on the Add an app window, click the Add button.   Add a firewall exception for flexsim.exe   Repeat the steps above for flexsim.exe:   Click the Allow another app… button. Browse… to your extracted license server downloads. Select flexsim.exe. Click Network types… and choose the appropriate networks to allow access to lmgrd.exe. These should be set to the same settings chosen for lmgrd.exe, and you can usually allow all network types - domain, private, and public. Click the Add button. Click OK to close the Control Panel window.   Port considerations   You may need to allow communication through other firewalls or network appliances, depending on your network topology and specific licensing plans for how and from where client PCs will connect to the license server. Usually for such firewalls or devices you will configure inbound and outbound port exceptions to allow your license server communications to pass through.   A FlexSim license server has its ports defined in a flexsim.lic license file, specified when you configured your FlexSim_Licensing service.   Our default ports are as follows:   lmgrd.exe - licensing service - port 26914 - TCP flexsim.exe - vendor daemon - port 56914 - TCP   There is a chance you specified custom your port numbers. If you're not sure you can check your flexsim.lic license file. Read more about FlexSim's license file and default vs custom port numbers in our article FlexSim's license file.

FlexSim 2023 Update 2 is now available for download. You can view the Release Notes in the online user manual. FlexSim 23.2.0 Release Notes For more in-depth discussion of the new features, check out the official software release page: FlexSim 2023 Update 2: NVIDIA Omniverse, USD, Restricted Models, and more If you have bug reports or other feedback on the software, please email dev@flexsim.com or create a new idea in the Bug Report space or Development space.

In addition to the animations that are on the Operator and Person flowitem by default, you can easily download and add more animations from Mixamo. Below are the steps to do that. If you want to create new characters with animations, see Bone Animations 1. Download the attached two files: FlexSim_Operator.fbx and FlexSim_F_Operator.fbx. These are the versions of the male and female operator shapes as exported from Mixamo originally, before they were modified and optimized in 3ds Max. 2. Log into your account at https://www.mixamo.com and press the Upload Character button in the Characters section of the site. 3. Drag the FlexSim_Operator.fbx or FlexSim_F_Operator.fbx shape from step 1 onto the window that appears. A progress bar will appear as the shape uploads to Mixamo's server. Once it is finished uploading, press the Next button: 4. On the Animations section of the site, select an animation you want to apply. Adjust the parameters as desired and press the Download button: 5. Select "Without Skin" in the Skin section and press the Download button. This will download just the animation file rather than the animation, the mesh, and the bones. The mesh and bones are already in the software so you only need the animation if you are editing the standard male or female operator shapes. 6. In FlexSim, edit the Animations for an Operator or a Person flowitem: 7. In the Animations and Components window, select Edit Animation Clips: 8. In the Animation Clips window, press the Plus button to add the animation you downloaded in step 5 above. Optionally, you can edit the animation clip's name and press Apply. You can also edit the clip's length or split the animation into multiple clips using this window. 9. Close the Animation Clips window when you are done. 10. In the Animations and Components window, add a new Animation and name it. Then add an Animation Clip to that animation. Then select the clip and set its Animation and Clip values to the animation/clip set in step 8: 11. Now you can use the new animation in your model on this operator or person flowitem.

To go along with the launch of Flexsim 2018, we've put together a few sample models to show some of its features. Internet Cafe internetcafe.fsm This model shows off several of the new animations added to the Operator and Person flowitem. It also demonstrates how the Create Person activity can be used to attach a Person flowitem to an Instanced Process Flow. People with yellow shirts are attached to the ComputerUsers flow. They acquire a computer desk and then have an employee bring them over to their computer. Those in orange shirts are attached to the FoodCustomers flow. They buy drinks or snacks at the counter and then hang out at the tables.

If you have bug reports or other feedback on the software, please email dev@flexsim.com or create a new idea in the Development space.

FlexSim 2022 is now available for download. You can view the Release Notes in the online user manual. For more in depth discussion and videos of the new features, check out the official software release page. If you have bug reports or other feedback on the software, please email dev@flexsim.com or create a new idea in the Development space.

The ideal way to access the User Manual is by viewing an electronic copy either online or inside the software. Online User Manual The User Manual is available online at docs.flexsim.com. There you can select a software version and manual language. We hope to provide additional languages in the future. In-software User Manual There are two ways to open the manual inside FlexSim: Click the User Manual button on the main toolbar. Click the Help menu and then click User Manual. Why the electronic manual is preferred The online / in-software version of the User Manual is better than a print or PDF version for many reasons, including: Regular updates - The electronic version keeps up with every new FlexSim release. A printed manual unfortunately goes out of date every four months with each new release of FlexSim. The online manual allows you to also view older versions of the manual. Animated GIFs - Animations enhance communication by making it possible to see FlexSim in real time. Animated GIFs won't work in a printed copy. Better search - The online version allows you to search the manual using Google. The in-software version also has a search program which is easier than trying to find relevant keywords within a large document. Styled and reflowable tables, images, and tip boxes - While these elements look good on the web, print or PDF versions don't always correctly format their placement within the document. Better organization - A printed manual won’t always maintain the same organization as the online and in-software manual, making it more difficult to navigate. Mini-table of contents - Each topic has easy navigation within each topic via inner-links. A printed or PDF mini-table of contents (found in most topics) can't function as a clickable index, making it difficult to easily skip to relevant sections within a topic. Printing topics from the User Manual While we don't recommend printing the entire manual, you can easily print individual topics for later reference. Print from the online manual Visit docs.flexsim.com using your favorite modern web browser. Use the table of contents in the left navigation bar to visit the topic you want to print. Use the printer button in the upper right of the topic window to print the page: Print from the in-software manual In FlexSim, open the User Manual and browse to the topic you'd like to print. Press the 'world' button to open the topic in your web browser. Choose the print function inside your web browser - depending on your browser, you may be able to right-click the web page and choose Print, or you can use the keyboard combo Ctrl+P.

If you have colleagues who should also have visibility to your license codes, you can "share" your licenses with their account. Licenses should only be shared in accordance with FlexSim's end user license agreement. When you share your licenses with another FlexSim Account, they are able to view all of your activation IDs in full, as well as the activation histories of those licenses. To share your licenses with another FlexSim Account, do the following: Log in to your FlexSim Account at https://flexs.im/account. In the navigation header, click the Licenses link, then choose Sharing from the submenu: Follow the instructions to add one or more FlexSim Accounts to share your licenses with. The FlexSim Accounts must already exist. Press the Add button to submit the accounts. When you submit, if you are navigated away from the Share page, simply revisit the Sharing link as described in step 2 above. You should see the results of your share attempt. You will also see a list of the accounts you're sharing with, as well as any accounts that are sharing with you: Your licenses will now be listed in your colleague's FlexSim Account. They will see your licenses listed on their Licenses page the next time they log in. If they were currently logged in to their account while you shared your licenses, they should log out, then log back it to note the change.

Introduction Several times per year we release a new feature-version of FlexSim Simulation Software. In order for your PCs to be able to run a licensed version of the upgraded software, you'll need to upgrade your standalone FlexSim license. Licenses with a current maintenance subscription are eligible to be upgraded to the new version. If you don't understand how licensing works for different FlexSim versions, please review our Answers article FlexSim Version Numbering. Overview After installing your new version of FlexSim, there are 3 main steps to upgrading your standalone license: Return the licenses you intend to upgrade Upgrade your licenses Activate the upgraded license Several of these steps have their own fully documented procedures. We'll link you to those resources below. 1. Return the licenses you intend to upgrade The steps to return a standalone license are fully documented. Choose the link below that best matches your needs, depending on whether your PC can connect to the Internet: Standalone - Return - Online Standalone - Return - XML / Offline Be sure to return ALL licenses you wish to upgrade. 2. Upgrade your licenses NOTE: Licenses with expired maintenance will not upgrade. Timed licenses do not upgrade. Only permanent (not timed) licenses under current maintenance can be upgraded. Log in to your FlexSim Account. If you were already logged in to your FlexSim Account, in the top navigation menu hover over your initials icon and choose Reload Account. Now in the top navigation menu, choose Licenses > List. Check that the available seat count is equal to the total. All of a license’s seats should be returned for it to upgrade. Click on the Upgrade Licenses button. If you have several licenses to upgrade and all are owned by or shared with your FlexSim Account, they will all be upgraded at once. Please be patient while the upgrade process works in the background. When the page refreshes, eligible licenses will have a new activation ID for the latest version of the software. Your license code indicates its version at the end of the code to help you know what versions your license will properly activate. Review license code format. You'll be able to use the upgraded license codes in the next step. 3. Activate the upgraded licenses The steps to activate a standalone license are fully documented. Choose the link below that best matches your needs, depending on whether your PC can connect to the Internet: Standalone - Activation - Online Standalone - Activation - XML / Offline If you have any questions or problems, please search our Answers Community for possible solutions. There is a good chance someone else has already asked your question. Still not finding what you're looking for? Submit a new question and we'll check it out. If you're including any confidential information, such as license codes, be sure to mark your question as private! You can also contact your local FlexSim distributor for live phone, web, or email help.

Run FlexSim "in the cloud"? Instead of provisioning a desktop or laptop PC that meets FlexSim's recommended system requirements, you may prefer for your FlexSim users to use a thin client PC which connects to a more powerful back end system that actually runs FlexSim. FlexSim does not test our products in such environments, so your user experience may vary. Meet the system requirements It is important that the remote system meet or exceed FlexSim's recommended system requirements. Usually for CPU and RAM that is not a problem. In the past, the biggest hurdle was typically graphics. Does the remote machine support hardware accelerated graphics, and support streaming those graphics to the thin client where the user is actually sitting? If the graphics are not accelerated, or if accelerated graphics can't be streamed to the user, then the system doesn't meet FlexSim's requirements and you may have a bad user experience. In the past In the past, provisioning such a system to meet FlexSim's requirements was quite a specialized combination of hardware and software. Even today not every cloud provider has the infrastructure to stream accelerated graphics. Our anecdotal experience is that such set ups are becoming more common among 3rd party cloud providers. Going forward Major players now seem to have mainstream support for hardware accelerated graphics: https://aws.amazon.com/ec2/elastic-graphics/ https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu https://cloud.google.com/gpu/ As mentioned above, FlexSim is not targeted to these environments and the software is not tested in these environments, so your mileage may vary. Conclusion With more and more cloud providers enabling hardware accelerated graphics, there is a chance that FlexSim could work well on a cloud-based platform. If you have tried running FlexSim remotely using one of these or another cloud provider, we'd love to hear your experience. Please comment below to let us know about your setup, what worked, and what didn't.

Have you received this licensing error?   Operations error: 7288 The activation of the fulfillment is denied by the activation policy because fulfill count exceeded the available seat count.     Here are some common reasons you may encounter this error, along with some possible solutions.   All seats are already in use   Problem: All the seats of this license are already activated. There are no available seats left to activate.   Solution: You must return a seat from a computer where it is currently activated. Once a seat has been successfully returned it is available for a new activation.   If you are not sure where your license is currently activated, there are two main methods for finding out:   Go on a hunt: On each computer where the license may be activated, check the license status by opening FlexSim and going to Help > License Activation > View Licenses tab > press the View Licenses button. This will show you the license information for the current PC. Check the history: You can view your activation/return history from your FlexSim account's licenses page. On the Licenses page, expand the folders until you can see the Activation ID you are trying to track down. Click the Activation ID to load the history for this license. This history includes dates/times of the activations and returns. If the information is available it will also list the computer name where the license was last activated and the Windows username of the logged in user who completed the action. If the computer where your license was activated has been stolen, destroyed, wiped, etc., please contact your local distributor to discuss a solution.   Activation ID is obsolete   Problem: You are trying to activate an obsolete activation ID. An activation ID can become obsolete if it has been cancelled, replaced, or upgraded.   Solution: Make sure to use the most up-to-date version of your license. Log in to your FlexSim account to view your latest license codes.   Consider the following scenario: You purchased a FlexSim license and were emailed a license code. You used that license on your laptop for several years, upgrading FlexSim as new versions were released and following the prompts to upgrade your license as needed. Now you have purchased a new laptop. You successfully returned your license from your previous laptop. On the new PC you installed FlexSim and needed to get it licensed. You looked up your original license code from your years-old email, but when attempting to activate you received error 7288.   The reason is that over the years as you upgraded FlexSim you also upgraded your license code. The old, original license code is obsolete. You must log in to your FlexSim account to get the most recent license code. With the new license code you are able to successfully activate your license on your new laptop.

Verify Connectivity   Issues with client-server licensing can often be traced to communication issues that prevent the client PC and server from communicating. The first step is to verify whether the client PC can connect to the license server over the licensing ports.   Even if you successfully establish connectivity, remember that server configuration or license issues can also keep a client PC from becoming licensed. See our Troubleshooting Tips article for guidance.   Basic connectivity (ping test)   On the client PC, click the Start button or press the Windows key, then type “cmd” into the search box in the Start menu, and press Enter. Windows will search for and open the Command Prompt.   From the command prompt, enter ping [server name or IP address]. For example, if your license server has a local IP address of 10.0.0.135, then type on the command line ping 10.0.0.135.   If you are referencing your license server by name in FlexSim software’s License Activation interface, use the same fully qualified domain name here instead of the IP address:     If your client PC receives a response from your license server, then the server is visible across the network, by name or IP address, from the client PC.   Advanced connectivity - ports test   If you can pass the ping test the next step is to see if the required ports are open for communication. There are a couple of methods you can use to test if your client PC can connect to your license server over the ports specified in the .lic file.   PowerShell Test-NetConnection   From Windows PowerShell, enter Test-NetConnection [server name or IP address] -Port [port number]. For example, if your license server has a local IP address of 10.0.0.135, and is hosting FlexSim licensing over our default ports 26914 and 56914, you should run the following two commands:   Test-NetConnection 10.0.0.135 -Port 26914 Test-NetConnection 10.0.0.135 -Port 56914   If both of these commands include in their response TcpTestSucceeded : True, then the required connectivity is available. Test-NetConnection documentation   Telnet   Check out our tutorial video at https://flexs.im/telnet that guides you through the basic steps of enabling telnet on your client PC, then using it to test port connections from a client PC to your license server.   Double check your configurations   If you can't establish a ping connection or a port connection, use the suggestions below to double-check your settings. Or perhaps you passed the connection verification checks but FlexSim Software is still not getting licensed? These connectivity tips may reveal the solution:   CLIENT PC SETTINGS - You may have a typo or otherwise have misconfigured the settings that point your client PC to the license server. Double check that your settings are entered using the correct format (single-user client PC, multi-user client PC).   PORT & ADDRESS - Double check the port number and server address/name used in activating licenses on your client PC. Make the port number specified is the number in use for your license service. Our default port number is 26914 but enter your custom port number if you set your own.   SERVER FIREWALL - Did you add the required exceptions to your license server’s firewall (lmtools, lmadmin)? To any other network appliances and firewalls (lmtools, lmadmin)?   Connectivity suggestions   You've triple-checked your client PC settings. You've set firewall exceptions. The port test still shows that you can't connect from the client PC to the server. What can you do?   These aren't fixes, but they can help you narrow the source of the problem so that you can find a solution.   CHECK THE LICENSE SERVER - Maybe your license server isn't actually serving your licenses. You can install the FlexSim simulation software locally on your license server, then using the port you specified (default is 26914) and the local IP address 127.0.0.1, you can point your local FlexSim installation to the local license server to see if your license server can license itself. If it can't, check out these license-server troubleshooting tips (where you'll also read about this local test troubleshooting method).   DISABLE FIREWALLS (temporarily as a test) - A connection issue could be caused by a firewall configuration problem on the client PC, on the license server, or on some network appliance in between. One at a time, disable intervening firewalls on the client PC, the license server, and appliances in-between, as applicable. With each disabled firewall, retest connectivity. If connectivity is established after disabling a firewall, work on that firewall's configuration, then reenable it. Test again. Repeat for each firewall until a connection between client and server can be established.   DISABLE ANTI-VIRUS (temporarily as a test) - Some anti-virus solutions will block application communications. Disable anti-virus software on the client PC. If nothing changes, also disable anti-virus on the server. If this fixes the issue, work with your IT administrator to modify your anti-virus settings. Remember to reactivate your anti-virus software after this experiment.   ASK YOUR FRIENDLY NEIGHBORHOOD ADMIN - Your network may have settings, topology, filtering, etc. that affect the client PC’s ability to communicate with the license server. Work with your network administrator to make sure the client PC can communicate with the license server across your network using both port numbers - for the licensing service and the vendor daemon. See default and custom port numbers.

FlexSim 2024 Update 1 is now available for download. You can view the Release Notes in the online user manual. FlexSim 24.1.0 Release Notes If you have bug reports or other feedback on the software, please email dev@flexsim.com or create a new idea in the Bug Report space or Development space.

Background   The method for licensing a single-user client PC saves client PC license settings to the Windows profile data of the signed in user, so license settings are saved on a per-user basis.   In cases where the exact number or identity of PC users is not predetermined, such as in a university computer lab, it is impractical to license users individually in this manner. Another use-case for this method is when FlexSim Software is automatically pushed or deployed to client PCs. Having the licensing as part of the deployment is useful.   For this mult-user method we'll use a license file on the client PC to license FlexSim software generally for any user of the PC.   Use a license file   Create a plaintext license file   On the client PC create a plaintext license file named flexsim.lic with the following 2 lines (exclude any line numbers):   SERVER 127.0.0.1 ANY 26914 USE_SERVER   If your Windows settings do not show file extensions, it is possible that your flexsim.lic license file is actually named flexsim.lic.txt, which will not work. Be sure to show file extensions and make sure your license file ends with the .lic file extension. The actual name of the file is not important (it could be helloWorld.lic, for instance), but it needs to end in .lic.   Modify   On the client PC, modify your new license file with the following changes:   On line 1 change "127.0.0.1" to the IP address or fully qualified domain name of your license server. If you modified your license server with custom port numbers, on line 1 replace the default port 26914 with your custom port number.   Install   With FlexSim software installed on a client PC, your new license file should be copied into FlexSim’s installation directory in the following location:   C:\Program Files\FlexSim <version>\program\   Your exact folder path could differ based on custom installation locations or FlexSim version, but it should be placed into FlexSim’s program\ folder.   Multiple license servers?   If your FlexSim licenses/seats are spread across multiple license servers, you can configure your client software to try to pull a license from any of your multiple license servers. Simply create a new license file for each possible license server and save each to the same program\ folder. In this scenario, in your program\ folder you would have multiple license files listed, like this:   flexsim1.lic flexsim2.lic flexsim3.lic etc. Each license file should reference a different license server and its port number.   Next   Check out the next article to learn how to verify that your client PC is licensed, and what to do if it isn't: License Server - Verify client PC licensing.  

You might be wondering what data is collected when you use FlexSim simulation software. How is it sent to FlexSim? How is it stored? What is it used for? Can you opt out?   Below you'll read all about it, but for those who can't be bothered:   tl;dr: Our customers have complete control when deciding what data is sent to FlexSim. Any data gathering is easily circumvented, disabled, or avoided.   If that interests you, read below for the details.   Introduction There are four ways your data may be sent to FlexSim, and there are workarounds you can implement for each to avoid sharing any data. Each link jumps to its section below: FlexSim Accounts (contact information) Licensing your software or your local license server (license and computer information) Online communications from the software (license and computer information) Support or model building services (customer-sent data) You can also jump to the Conclusion.   FlexSim Accounts We receive user personal contact information when someone signs up for a FlexSim account, or when an account is created for a person in order to give them a license. FlexSim Account information includes required fields (name, email, organization, country) and optional fields (including title, address info, phone). These data are submitted to FlexSim through web forms. Our website is only accessible via HTTPS, with TLS 1.2 or higher enforced. FlexSim's databases are hosted in United States data centers, and this data is encrypted at rest with LUKS (Linux Unified Key Setup) in default mode aes-xts-plain64:sha256 with a 512-bit key. Data is encrypted in transit with SSL. FlexSim US's CRM is HubSpot, and US contacts are saved there. HubSpot ensures that your data is encrypted at rest. HubSpot's sites and services are accessed via HTTPS and we've configured our account's security settings to require TLS 1.2 or higher. Contacts from outside the United States are forwarded to their regional FlexSim distributor, who operate independently and may use a different CRM. Our websites track usage information to help us improve our marketing and fix site issues. Basic web browsing logging data is collected, such as IP/location information, browser type, session duration, etc. Additionally, if you are logged in to your FlexSim account, we keep download, license, and profile logs. Check out Autodesk's privacy policy. Workaround A FlexSim Account requires a person's contact information for convenience only. If a customer wishes, an account can be set up with a generic name, like "CompanyXYZ FlexSim Rep," and a generic email, like "flexsim@company-xyz.com". Having a real name and email of an actual person is convenient, but also optional. As long as we have a way to communicate with a customer, that works!   Licensing License codes When a client PC communicates with our main license server to activate or return a standalone FlexSim license, it does so over secure HTTPS.   When licensing a local license server using the licensing utility flexsimserveractutil.exe license codes are transmitted in plaintext over HTTP. This means that license codes are transmitted in the clear. The risk to a licensed user is that if your online communications are being monitored your license keys could be compromised, allowing someone else to obtain your FlexSim license keys and potentially use them to activate your FlexSim licenses and consume your seats, leaving you without the ability to activate those seats normally.   If there is ever an issue where a license should be available but for some reason is not successfully activating, customers can contact their local FlexSim distributor for licensing support. These situations can be handled quickly.   License codes are stored in plaintext in FlexSim's main Flexnet Operations server database.   Additional license history information When a license is activated over the Internet, whether by a client PC (standalone license) or when configuring a license server (server license), FlexSim also receives the Windows username of the person logged in doing the action, and the Windows computer name where the license is being activated. When activating a standalone license this information is first AES-256 encrypted before transmission over HTTP. For a license server the username/computer name are transmitted in plaintext over HTTP. Once received by FlexSim, the Windows computer name and username are stored in our database which is LUKS encrypted at rest and are displayed to the customer in their account's license history. The license history allows customers to track license usage and location - a useful feature requested by our customers to help manage standalone licenses shared among multiple people.   When activating a standalone license over the internet, the software also sends basic operating system and FlexSim software version information, which, like the Windows username/computername, is AES-256 encrypted before being transmitted over HTTP. This additional information is AES-256 encrypted at rest.   Workaround We have an alternate method of licensing that applies to both standalone PCs and license servers where a user generates XML requests and manually submits them to FlexSim's website over HTTPS using TLS 1.2 or higher. Licensing by XML avoids the following potential issues: License codes sent in plaintext over HTTP FlexSim receiving Windows username and computer name information, and in the case of standalone licensing, additional operating system and FlexSim software version information. Manual licensing is somewhat less convenient and more time consuming than online licensing - instead of just a button push there are several steps to follow in sequence, including generating requests, uploading requests, downloading responses, processing responses. It is up to you to decide whether easy-online or manual-XML licensing is most appropriate for your organization.   License operations, both automated/online or manual/XML are documented in our article Licensing Procedures.   Online communications Start page FlexSim software has a web-based start page that by default sends basic computer information to FlexSim to request introductory content to display when starting the software. This information includes FlexSim version, and general Operating System properties including Windows version, language, and country. These are used to display appropriate content to the user. For instance, we have localized versions of the start page depending on the country and language settings sent by the client PC. If a computer is licensed, the license information along with Windows username and computer name are also sent, again for a history of license use, and also in the case that FlexSim needs to display specific information only to licensed users, such as expected maintenance windows for FlexSim's main license server, etc.   The start page is enabled by default. The above-described information is AES-256 encrypted and then transmitted to FlexSim over HTTPS using TLS 1.2 or higher. The data remains AES-256 encrypted at rest.   Telemetry A user can also enable additional telemetry as an opt-in feature. This sends additional operating system and hardware information such as CPU, RAM, screen resolution, GPU type and driver version, all of which helps us build an aggregated view of the computer capabilities of our user base. This is useful for development decisions, to make sure we target the simulation software to hardware that is generally available to a majority of our user base. This telemetry info is AES-256 encrypted, transmitted to FlexSim over HTTPS TLS 1.2 or higher, and stored in AES-256 at rest.   Workaround: The start page can be disabled with an in-software setting. Additional telemetry is an opt-in feature. You can read more about online communication in our Sofware License Agreement, item 15. Online Communication. The in-software settings are configured from FlexSim simulation software's main menu > File > Global Preferences > Dynamic Content tab.   Support In the course of using FlexSim simulation software, your simulation engineers may send models or other data to Autodesk's FlexSim support team for help via email, or by posting to this online community.

As many of you have seen from our youtube video, we recently released an early beta version of a new FlexSim Agent module. This module can be downloaded from the Downloads section of your FlexSim account, under the Modules tab. Note that the Agent module will only work properly with FlexSim 20.1.1 or later. Here I'm posting some of the models I created and showed on the video. BasicProximitySystem.fsm TwoPhaseAGVSystem.fsm OnePhaseAGVSystem.fsm Boids.fsm AStarSystem.fsm RoomEvacuation.fsm HallwayTravel.fsm The AGV models aren't perfect (there's some tweaking needed, and there are some bugs that need to be fixed), put I'm putting them out there anyway. Since this is a beta version, I'm going to just upload unannounced module updates to the downloads section, so you can check the dates/versions on the downloads page against the version you have installed if you want to get the latest and greatest.

Background   Often a client PC is used by a single user who should have access to change license settings.   This method saves licensing settings to the user’s Windows profile. In this manner licensing is saved on a per-user basis and should be completed in advance for each FlexSim user on this client PC.   In some situations it is better to license the PC once for any user who might log in. This can be the case for a university computer lab, for instance. If your situation would be better served by licensing the software one time for all users of the PC, please check out our guide to license a mult-user client PC.   Configure Licensing   To license an individual Windows user, do the following while logged into Windows as that user:   Open FlexSim software on the client PC by right clicking the program icon and choosing Run as Administrator. You won't normally need to start FlexSim under elevated privileges, but sometimes licensing the PC for the first time requires it. Go to the software’s main menu and select Help > License Activation. Navigate to the License Server tab. Check Use concurrent licensing. Enter the License Server Address using the form port@host, where host is an IP address or fully qualified domain name (FQDN). For example, if your license server is reachable via the FQDN licenseserver.mycompany.com: If you used FlexSim’s default license service port number, enter 26914@licenseserver.mycompany.com. If you specified a custom port, use that number instead. For example, if you entered 27500 as your custom port number, you should enter 27500@licenseserver.mycompany.com. Click Apply Configuration.   Multiple license servers?   If your FlexSim licenses/seats are spread across multiple license servers, you can configure your client software to try to pull a license from any of your multiple license servers. Simply enter all available license server options, separated using a semi-colon, like this:   26914@lic.server.one;27001@lic.server.two;27009@lic.server.three   Here is an example image:   The software will attempt to contact each license server in turn until it obtains a seat or has attempted all license servers and failed.   In the example above, lic.server.one and lic.server.two are fully qualified domain names to properly configured license servers, with lmgrd serving on ports 26914 and 27001 respectively. You could also use an IP address instead of a FQDN.   Next   Check out the next article to learn how to verify that your client PC is licensed, and what to do if it isn't: License Server - Verify client PC licensing.

Failed to connect to the license server Have you ever encountered this error? ERROR: flxActAppActivationSend - (50041, 41143, 34) "Failed to connect to the license server or Operations server. Recover: check connection and that server is operational." This error indicates that your computer is not able to communicate with FlexSim's license server. If your computer is purposely air-gapped, please use the Manual XML licensing methods listed at the bottom of this article. Protocols, ports, and addresses A license activation or return will attempt to make HTTP (port 80) and HTTPS (port 443) connections, currently with the following servers: license.flexsim.com www.flexsim.com sw.flexsim.com sw1.flexsim.com Make sure these communications are allowed on your network. To make sure you maintain compatibility with any possible future changes to our server configurations, consider configuring your network to allow communication with any *.flexsim.com subdomain. Troubleshooting Any of the following could prevent your FlexSim software from communicating with FlexSim's license servers: Your computer is air-gapped or otherwise blocked from communicating over the Internet. The FlexSim software is not allowed to communicate over the Internet. FlexSim's above-listed addresses are blocked on your network or computer. Your network communicates through a proxy service but you haven't configured the proxy server settings inside FlexSim. FlexSim's license server may be down due to some outage or maintenance. Let's look at solutions for each possibility: 1. No communication / connection issues If your computer is disconnected from the Internet, you will need to connect in order to activate or return a license online. If this is not possible, please use the Manual XML licensing methods listed at the bottom of this article. You may also see this error if you're on a flaky wi-fi connection, or a slow network connection. The communication must be solid enough that it does not time-out, where the client software is able to receive a response in a timely manner. If you are connected to the Internet but on a slow or unreliable connection, you can fall back to the Manual XML licensing methods, or you can retry the online activation multiple times - it may eventually complete successfully after several attempts. 2. FlexSim's communications are blocked If your computer is connected and you can visit other sites, but FlexSim's licensing actions are still blocked, it could be due to an anti-virus solution or other security measure preventing FlexSim's communications. Work with your IT team to disable such measures and test if FlexSim is allowed to communicate. If so, configure your security measures to allow FlexSim to communicate for licensing purposes, or if that is not possible, use the Manual XML licensing methods listed at the bottom of this article. 3. FlexSim's license server is blocked Perhaps one or more of FlexSim's license server addresses (listed above) is blocked on your network. This could be a deliberate blocking of a specific address, or more likely a general block of a wider range of sites or IP addresses. Work with your IT team to determine if this is the case and if the block can be removed. If that is not possible, use the Manual XML licensing methods listed at the bottom of this article. 4. Proxy is not configured If your network settings require that FlexSim communicates through a proxy server, you'll need to configure the software to do so. For FlexSim version 23.0 and higher you'll do this directly in the software. From FlexSim's main menu, navigate to Help > License Activation > Advanced > Proxy Details. Fill in your proxy server information and click the Apply button. If you're using an older version of FlexSim, you can download this attached model. This is an older model file compatible with FlexSim version 5.0 and up. It has a Model Control GUI that is an extension to the License Activation window that includes this extra tab where you can put proxy details. proxy-details-v5.fsm 5. License is already activated but fulfillment is broken The license you're trying to activate may already be activated on your computer, but in a broken or unusable state. Follow the instructions for your license hosting situation to remove the broken fulfillments: Standalone - Delete fulfillment License Server - Delete fulfillment 6. License server offline There are circumstances when FlexSim's main license server can go offline. Most commonly this is due to regular updates or patches being applied. In this case the server will return to normal operation shortly. Please be patient and try again in a few minutes. In cases where longer maintenance is planned you will find a notification at the top of this community indicating the purpose, date/time, and expected duration of such maintenance. This notification will be given as early as possible to help you plan around such downtime. In rare circumstances an outage could be caused by a failure in one or more of the license server's databases, operating system, server hardware, networking, or data center. When such an outage occurs, we will post a notice at the top of this community and work to restore service as quickly as possible. Help! I need support! If none of the above suggestions work for you, please start a new question and include as many details as possible about what you've already tried and what you see happening. Please be aware that if FlexSim's license server is online and other clients are able to activate and return their licenses successfully, that the issue is within your organization's network or on your computer. The proper place to turn to for support will be to your own internal IT teams. The above information, including the protocols, ports, and addresses and the different troubleshooting suggestions should be enough information to solve the issue. Manual XML licensing If you are not able to allow FlexSim to communicate over the Internet, please use our manual XML activation/return methods for offline systems: Standalone - Activation - XML / Offline Standalone - Return - XML / Offline License Server - Activation - XML / Offline License Server - Return - XML / Offline
