virtual wind tunnel always get stuck at 0.02%

Altair Forum User

Hi;

i am trying to solve problem with Virtual Wind Tunnel but always get stuck at 0.02% even though i did check carefully for error.

Here is my file for very simple case, but still stuck at 0.02%.

Please help!!!

Please try the troubleshooting tips mentioned in ;

I tested your .stmod and it is running with VWT 2017. Do you have AcuSolve installed on your machine and is the path to AcuSolve correctly mentioned in your VWT Preferences?

So no issue with the model, very likely an installation issue on your machine. Please try the steps mentioned in the link above.

BTW, Wind tunnel dimensions have to much larger than what you have specified, else the default images might not look so good.

Also send a screenshot of how the folder where your case is running looks like. This would give an estimate of where the VWT is stuck.

the folder doesnt contain vwtAnalysis.MeshSim.txt

I am guessing this might be an issue with 'space' in installation paths and the run folder.

So best would be to install AcuSolve not in 'Program Files' but a folder like c:\Altair...

Also do not use 'Documents' folder for the run path, as internally at times it is interpreted as the old windows style 'My Documents'.

Old windows issues....

Interesting.

Did you manage to solve the issue?

I manage to run the car tutorial but solving gets stuck at 0.02%.

ydigit

Do you happen to have installation of VWT or AcuSolve in a path with 'space' or 'Program Files'?

Is your run path 'My Documents'? All these are still a problem for VWT to handle due to whitespace.

Please post a screenshot of your VWT Preferences edit > preferences > acusolve (in analysis)

Hi,

I have the same Problem. VWT always stucks at 0.02%.

The Troubleshooting tips mentioned before I have already checked.

- So there are no files like mesh_intersections.dat and/or mesh_intersections.nas in this folder

- Also I can find the following section in the vwtAnalysis.MeshSim.txt file

acuMeshSim: --------------------------------------------------------------
acuMeshSim:              Number of Nodes =
acuMeshSim:           Number of Elements =
...
acuMeshSim:            Total Memory Size =e+002 Mbytes

- The Folders CAD.DIR and MESHSIM.DIR also were created.

- In addition to that I checked if there is a smooth intersection between the wheels and the ground of the windtunnel.

- As a model I choose the VWT_Roadster from ther VWT-Library.

- In the attached picture below you can see the preferences I made.

- In the vwtAnalysis1.txt file I found the following, perhaps this could lead to an solution.

The problem is with

acuPrep: *** ERROR: Eddy viscosity must be non-zero at inflow boundaries.

Please update to AcuSolve 2017.2 and additionally install the hotfix 2017.2.1

This issue should be fixed there.

macorman06

I have the same problem. I installed the latest version AcuSolve 2017.2 and the hotfix 2017.2.1 and the error persists.

Can someone help me?
