When observing model results during the solving phase, one knows quickly if something is not right (boundary condition, material assignment, etc.).  It would be helpful to "pause" the simulation to update these issues and then resume or re-run without the need to download / upload the simulation results between changes.  The cancel option is useful sometimes, but the meshing procedure must be repeated afterwards.

Also, when a simulation is complete, there should be an option of making changes and resuming prior to downloading the results.  If, for example, I want to run additional iterations for flow or heat transfer, currently I must wait for the download to complete, make my updates, then upload the latest results for the simulation to "resume."  This wastes time and bandwidth.  Results on the 360 server should be maintained for some period until the user decides to download the results.

Support fully developed flow for a mass flow rate boundary condition.

When you clone a design with many scenario sometimes you don't want to clone everything.  The ability to select clone all or clone selected so we could pick which ones to clone would quicken the cloning process.  One example you wouldn't want to clone everything is when you are cloning after running a model that you saved cycles with adaptation.

With the release of 2014 the XYZ triad was removed from the navigation cube.

Please bring this back as it is very useful when setting up models and you need to determine what your basic flow direction is.  Now you need to zoom back out to look at the larger triad or find the origin triad and remember what the colors represent.

Two issues with the latest version of CFD 2014, UI Navigation Preferences:

1.  in Simulation CFD mode - the zoom CTRL + RMB is reverse order of 2013 (i.e., in 2013 pulling down zooms in, but it zooms out in 2014, yikes).

2.  The zoom sensitivity is MUCH faster than in 2014.

Couple these two together and it makes dynamic zooming nearly impossible for us old-timer CFDesign users.

With the addition of the solar heating to simCFD 2013, it would be great to be able to include the absorptivity in the material properties (in addition to emissivity).   A lot of materials deployed in the outside world have very different emissivity/absorptivity ratios on purpose.  Although you can trick the solar flux in the flag manager, it would be easier/more useful if you could just assign a material property called 'solar absorptivity' and let the user assign a value.  That way, if there are multiple materials with differing absorptivities in the same model, the setup and results would be easier/more accurate.

I would like the collapsible Materials/BCs/ICs/Motion/Groups folders and subsections to stay how you left them, or at least auto collapse. I've realised I spend a large amount of time collapsing 'Material' and then each group in turn to easily access the ones at the bottom - all subsections auto expand when you assign parts to a group.

Thanks all

I want to be able to edit the part names of any geometry within the CFD UI.

In the Design Study Bar under Scenario 1 --> Material --> Unassigned --> ‘Part Name’, I want to be able to right click the ‘Part Name’ and I want a menu item which says ‘Rename’ (much like what is seen when ‘Scenario 1’ or ‘Design 1’ are right clicked).

See attached screenshots.

Thank you,

Rebuilding the mesh definition can be a useful workflow when you want to modify the mesh history and perform sensitivity studies.  One issue that slows down this workflow is that if you have mesh refinment turned on before you rebuild the setting is lost.

I think it would reduce the chance of error if when if you rebuild it reuses this setting and when the edge sizing is finished the surface refinement is automatically applied as well so you don't have to click on refine again to eliminate the warning icon.

I can be helpfull to show suppressed elements in results, but they must be turned on one by one. Please allow users to select all or a group and check the "visible" box all at once.

When I clicked the CAD Entity Groups function (from SolidWorks which is my CAD tool) and if there are existing groups, I noticed those groups in the pop-up window "Grouping Geometric Entities" were auto-expanded and the highlighter was always rested on the bottommost group. If I wanted to check or review a particular part or parts in a specific group, it would require me to do the following processes:

1. Click and hold the window, then move it toward to a more central area of screen. This is because it always popped up on the upper left corner of screen where it blocked the SolidWorks FeatureManager design tree.
2. Hold the LMB (Left Mouse Button) on the window's slider bar and move it all way to top.
3. Click the "-" sign in front of each group to collapse it until all groups were collapsed so that I could see all existing groups.
4. Look carefully at all groups because it seemed to be sorted in an order unknown to me, and locate the one I need. Then I finally could expand the specific group to examine its contents.

You can imagine this is a quite tedious an inefficient process. I would suggest the following improvements:

1. Let the window popped up at the place where it was closed last time. The default position could be set at the center of screen, as almost everyone's design tree is on the left-hand side of screen regardless what CAD tool is being used.
2. Sort the existing groups alphabetically.
3. Make those groups initially auto-collapsed, and rest the highlighter on the topmost group.

After expanding the specific group that I went to examine and found a few entities required to be removed, I could only remove them one at a time. If there were Ctrl+LMB and Shift+LMB functions to allow multiple selections at a time, it would increase the user efficiency by aligning with the Windows experience (my OS is Microsoft Windows based).

Now, say, I also wanted to create a new group. I went to start picking entities for that group. I could see the first picked entity shown under the new group name. As I went along picking more entities, it appeared to me that they were not shown up in the Grouping Geometric Entities window. Then I realized the slider bar was slightly moving while I was picking more entities. It turned out those picked entities were appended in the same group under the first picked entity. This process would made the verification of entity picking harder. I would suggest that rather making the slider bar moving, it might be easier to verify if the entire expanded group were moving upward so that the newly picked entity would always appear at the bottom of the visible region inside this window.

This is how I would hope the CAD Entity Groups could be improved.

Hi,

May I request that a Velocity Wind Profile be implemented in the next 6 months? This is required for the AEC industry in Singapore. Thank you.

View Tab: Hide large axis or Hide small axis button (Currently the Axes button hides both axes)

 BEFORE pushing the "Axes" button in the View tab:

Both the large axis (large red box) and the small axis (small green box)are shown.

-----------------------------
 AFTER pushing the "Axes" button in the View tab:

Both the large axis (large red box) and the small axis (small red box) are hidden.

-----------------------------
 IMPROVEMENT:

There should be an option to include or hide either one of the axes. So if the user wants only the large axis or only the small axis, that can be possible.

See attached screenshots..

Thank you,

Now you get one vector per mesh node. In Areas with small mesh elements ther eis nothing to see excapt vectors.

On the top menu bar under  SETUP - SELECTION  a Hide and Show feature should be added.  It should work by allowing a user to hide or show the geometry that has been selected on the selection window.  It should not matter if its a Material or Boundary Conditions, all objects that shows up on the list can be hidden or if hidden be shown again.

We've heard from several folks that an automatic report generator would be a valuable addition to Simulation CFD.

We'd like to get a better understanding of how much demand there is for this (+kudos if you agree!) and what an ideal report generator would look like from your point of view (leave your comments!). How do you use reports today? How would you use reports differently if you could generate them automatically from Simulation CFD?

Moving a plane back and fourth in a model is a great way to see the results holistically. I'd like to export a dynamic image or a movie file in which the plane does this repeatedly; similar to a trace set.
