It is not clear which fields on the edit dialogs are editable, as the table appears entirely flat aside from a couple ellipses that hint at dialogs:


     Materials Edit


However, when you click in an interactive cell its input control is then exposed. For example:


     Materials Name Selected


     Materials Material Selected


I am proposing these controls are shown by default so it is clear which fields can be edited, and in what fashion.

I created groups during simulation setup, and I now what to access these in results. Currently this is only possible with wall results.


For example:

  • in an architectural application I want to show my structure group as a solid color while displaying vector and plane results through the space
  • in an electronics application I want to make my chip group all into summary parts

I've heard a couple requests for a formal certification program, so requesting futher comments here.


Are you interested in being certified? What would your expectations be? Are there other programs you have been through that are good models?

I want to use a linux cluster to solve Simulation CFD analyses. 


If you vote on this one, please add a comment about the cluster you intend to use!

Mesh history improvements

Status: Comments Requested
by Employee on ‎03-06-2013 11:05 AM

In Simulation CFD 2013 we introduced mesh history in the design study tree. We're curious how this feature is working for you and what could make it better.


These are some of the suggestions we received prior to having the IdeaStation:


  1. Be able to add a surface/solid to a mesh history branch. I created the adjustment but forgot a surface/part that I wanted to include there. Drag and drop the branch onto a surface or part would be consistent with some of the other setup tasks.
  2. Reorder mesh history.. Right click > move up/move down
  3. When you delete the 'automatic size' level you do a rebuild you get a manual mesh. Interesting consequence, but you eliminate all your history. May want a warning when deleting the automatic size part of the history.
  4. When you right click on the surface/gap, length scale and go edit. Actually edit those. If you do it to surface it would switch it from false to true.. Length scale would open the diagnostics window.

Do you agree (+ kudos)? Do you have other ideas?

Users asked for the possibility to set more standard settings, especially for turbulence models and advection schemes.

Could you have a look at the "triggers" functionality and see if this would fill this need? This was added to the API with the 2014 release.

Non-planar Bulk Calculator

Status: Comments Requested
by bravo03 on ‎04-23-2013 08:27 AM
I would like to be able to calculate the flow rate using a radial perspective.

Think of measurements coming of a radial fan and being able to measure the flow going linear and radial.

Current Workflow:
Create a multi-sided polygon and then use bulk-calc to get the flow rate through each surface.

I see this question rise every training: how can I hide/unhide all my aluminum parts...


(apart from creating a group).

A few ideas about the mesh refinement regions,...

1- Assign a unique color to each mesh region, this would help adjusting the sizes and relocating the regions.


2- Show region number under Mesh History in Design Study Bar, also show that number on the graphic area.


3- When editing an existing region the old one is still in the design tree (the old one doesn't get updated somtime).


4- Under Mesh History in Design Study Bar, there should be a "Spread changes" check box for each individual region, but usually there is only one for all,... 


5- Editing a region from the Mesh History (under Design Study Bar), the manu is different than the menu available in "Automatic Sizing" in the "Panel Buttons", and the spread changes button is missing!.

Also the mesh size text box is not responsive and won't get updated correctly.

Thanks for the feedback, good ideas!


I'm opening this to comments so others can add their thoughts as well.

It would be useful to have the ability to choose a 3D region of a model that would be read into CFD, rather than the current approach of reading through everything that is on-screen.


For instance, a large building in Revit with lots of detail, we may wish to run an analysis on a small 'L' shaped room buried in the centre. If we had functionality that allowed us to sketch a bounding box around that region and only read this into CFD it would be very useful.

The light grey color for unassigned materials can be hard to spot when applying materials in the model window during setup. The background is a grey gradient, and many database materials are similar in color which complicates this future. 


Suggestion is to show unassigned materials as a standout color (e.g. hunter orange), or better yet with a pattern that is not duplicated by the solid-colored options for database materials.

I can show parts in results as a solid color or texture. I would like to do the same for planes, iso surfaces, and traces so that they stand out against other results.

The mini toolbars disappear quickly if I am moving the mouse around.




I suggest making these more persistent; that is, they dont disappear as easily/quickly. Even better would be a setting that lets me make them either persistent (i.e. they don't hide) or specify a time/distance parameter before they disappear.

I would like to be able to color traces with a different result than the global result.  For example, I often wish to have cut planes and traces colored by velocity or temperature, but have the global result show pressure.

Treatment of conical strainers

Status: Comments Requested
by *Expert Elite* on ‎03-13-2013 04:17 AM

We deal with conical filters made of perforated sheet a lot and currently, the only way to model them is to use surface resistances. Now, often this can be a significant simplification since:


  • the velocities are averaged before the strainer to be applied in the Darcy's equation (instead of choosing only normal components)
  • all the streamlines are made perpendicular to the strainer surface as the fluid leaves it, which can be unphysical since there is no expense of pressure/energy in doing so

I would like to use a porous volume of conical strainer, with finite constant flow through coefficient in "Flow direction" and very large (1e8) coefficient in "Flow directions (1 and 2)". And I want to specify the conical surface of the cone to specify the cone direction, which is not exactly radial!


I tried using radial option in this but surprisingly, the fluid doesn't "see" the strainer nad behaves like it's fluid region!


Hope I see some improvement here.
