The environment of the Stress Linearization at Simulation is currently very poor comparing it to Revit or AutoCAD configuration (such as Zoom, Pan, Rotate, Orbit tool).
Should have the same configuration of the FEA editor, at least.
Other difficulty is how to pick nodes for the SCL when they are internal to the model (at comples models, such as bridges). You can use Clipping Planes to cut the model, but there is always the right angle and the steps to cut sometimes are not well defined (maybe a control of the value of the step the plane moves) for the User Interface.
Most of the time is very difficult to transfer results to a client. I usually do a report but sometimes they want to explore all the model. A result viewer that we can share with a client will be a tool to explain the results of a simulation
Currently, in the Job Manager, we can right click a job and select Log from the menu to get a very high-level log of the analysis. When a job fails, this high-level log is not enough to gain any insight as to why the job failed. I have to load the fem or pick around in the file folders for various text files.
I'd like to be able to open any relevant log or summary file related to the selected job using the RMB in the Job Manager. This would give me a centralized, cleaner interface when interrogating failed jobs. It could also give me a quick look at successful job results too, without having to open the fem fully.
Others have suggested improvements to results visualization or sharing. Maybe the above could be incorporated in a more substantial expansion of the Job Manager that could include improvements to results sharing or quick-reviewing.
I'd like to be able to look back at other design scenarios in the FEA Editor tree while I'm building/working in a current scenario. It might be enough to simply be able to expand other scenarios and not actually inquire on them or see their parameters. However, it would be nice to be able to look back at an earlier scenario to see what load values were used or what element types or definitions were used without having to "load" that other scenario.
I'd like to be able to quickly see the 3D visualization of beams while in the FEA Editor without having to run 'Check Model' to see them in Results. Running 'Check Model' on a beam- or truss-only model is generally very quick and not a problem. However, I'm using more mixed meshes now and many are very large models. So the Check Model step just to see if I have all the desired beam cross-sections and all the right orientations can take a while.
When performing a modal analysis, you can get a lot of modes with low or near zero mass participation. The results is a lot of garbage data. When moving on to a random vib or other vib analysis whose input data is from the modal run, the inputs are overwhelming to the solution.
The suggestion is to put a threshold parameter of "minimum reported mass participation" in the model that will delete the results under that threshold, thereby delivering a clean input set to the random vib analyses.
Some time you have a skeleton from FrameGenerator that you need to analyze more deep than Frame Analysis.
It would be very useful to send a part to SIM MECH that contains 2D or 3D Sketches.
Then at Sim Mech, uses beam elementos to simplify the modelling....
We often use different Design scenarios to analyze the same geometry with different loading combinations.
Ideally we would just use one Design Scenario and multiple Load Cases. Since a load can only be applied to one Load Case, it forces users to either duplicate the loads if used in multiple combinations, or use the Combine Load Cases tool in the Results Options which increases the complexity of a project.
I would rather see an option that let users assign a load to multiple load cases in the load creation dialog.
This could be done by using commas between the load case numbers, or a more advanced dialog that is similar to the Combine Load Case tools were a table of load cases and multipliers could be entered.
Or perhaps a new tool that is separate from the dialog boxes could be created. The user could assign different loads to Load Cases and use multipliers in a table. The loads could be assigned to named groups(ex. Live Load, Dead Load, Pressure) and those groups could be used in the tables as well.
With named groups you could export commonly used combinations (ex. 1/2 Wind + LL + DL) and import the combinations in new models. Any loads created could be assigned to the appropriate group and the combinations would be automatically configured.
Currently if the model changes, we delete all of the design scenarios except for the 'Base DS', change the Base DS and recreate all of the loading combinations in new design scenarios by activating or suppressing the necessary loads and constraints.
A feature or tool like this would significantly reduce design times, especially when geometry changes arise.
I think this option was made when the graphical preformance of a computer was not strong enough, but now I would alway's like to turn it on.
When adding thermoelastic material properties, have the ability to pull some of the properties from the material database. This would make a good start in adding the rest of the properties & would also serve as a double check that the manually added rows are close, especially when units conversion in a problem.
I often need to work with models that contain a big number of parts (solid or surface). And speed of interactions with Autodesk Simulation are very slow.
You need to import an assembly or comlpex part - wait for a long
You need to change property of parts (thikness, material, type of elements ...) - wait again.
And so on.
Compared to other CAE software, such as Ansys, Femap, Abaqus it is look like an AS parking brake is not off.
whether this situation will change for the better in the future?
I would like the ability to work on one design scenario while another scenario is busy doing something else.
For example, if a model is meshing in design scenario 1, or if the analysis is running in design scenario 1, I would like to be able to setup a model in design scenario 2, 3, whatever.
When on the search tab of the Autodesk Simulation Mechanical Help, it is possible to choose from certain areas to search in for returns of topics. The current list is; Everywhere, Getting Started, Learn & Explore, Downloads, Troubleshooting and Installation & Deployment. I would like to be able to narrow this search only to the core documentation written for the software. I would like this pull down list needs to have an option for "User's Guide" only.
The capacity to simulate a transient travelling weld over a line in the old version we have to write a script to do this automatically but that is not possible anymore . A load to apply a travelling heat source over a selection of nodes or line will be helpfull to simulate weldings. At the moment i do it but i have to select node by node.
If you have built a FEA model with beam elements, and those elements have beam offset, and axis specific orientation when you try to add an new element where need to intersect a beam element or a need to build a connection between nodes, is very hard to do that, because the software doesn`t respect your defined beam offset and axis orientation.
It will be nice that after using the commands:
The software would be detect what is the intention of the FEA model and respect the beam orientation and Beam offset.
Please see this video:
It would be awesome if you can add more units. Like tons etc. And add a weld connections. Like weld mesh generator. Like if we click on an edge we could add a weld in it and define what type of weld and put thickness to it. And add more materials please. AH36 etc. And make it even friendly user. Surely if you could done this properly you could beat others software.
Thanks and more power Acad. sim.Mech,
