hi everyone,
I have got an issue with ideasUnvToFoam.

I am trying to convert a UNV mesh generated with salome using the above converter. However, I continually get the error:

I have had a good look at the example files in the utilities folder but they seem to have exactly the same structure.. is this a bug in ideasUnvToFoam?

Any ideas?

All the best,

Chris

Hi again,

I think I narrowed down the problem but still don't understand why ideasUnvToFoam won't work. Any help would be really appreciated.

I constructed a test case, consisting of a simple block. Now, in Salome, if I define only the "Walls" of the box as boundary faces, ideasUnvToFoam works fine. However, as soon as I define the volume in between the faces the converter stops with an error as printed above.
Now one might say, don't define the volume then.. In my case, I have to different volumes in a room that have different temperatures and pressures... The easiest way I could think of this was to define two different boundaries... Any other ideas?

Many thanks,

Chris

Hi

Could you post the Salome script? then its easier to have a look.

It sounds like you have two volumes which are connected in some way? correct me if I'm wrong. I don't think the ideasUnvToFoam converter supports multiple volumes. So export them separately and connect the BC using Ggi from 1.5-dev or stitchMesh.

Hi,

I also have an issue with conversion using a UNV mesh generated with salome 6.4.

Funny thing is, I get different error messages using OF 2.0.1 and OF 2.1.0.

Can anyone help me understanding this problem?

Here with OF 2.0.1:

Hi everyone!

I'm working on a simulation too, and it appears the same mistake:

I'm defining the inlet, outlet and walls volume , but I can't find the solution of that problem yet. If anyone has solved it, I'll appreciate your help.

Thank you very much.

Hi, Did you ever manage to find the cause of this error?

I am also stuck with this issue.

Thanks,
Alex

Hey all,

After making some trial-and-error cycles between Salome and OpenFOAM, I have solved this problem by simply deleting existent "groups of faces" and recreating new groups under the same mesh (Mesh_1 for example). Some faces must have been misaligned whilst processing in Salome. It's certainly worth trying this out, thereby narrowing your troubleshooting down. Cheers!

Hi again,

Similarly to the reply above. I solved the issue by deleting some edges from groups in the Salome mesh. For me this causes a bug where Salome refuses to export the mesh as a UNV but I get around this by saving the case and reopening.

Openfoam incorrectly identified points on Z directional edges assigned to a geom group, as face zones.

This worked! I was also facing the "FOAM exiting" error, so I went back to Salome and deleted a group of edges in the mesh (it was the only one). Now, the OpenFOAM mesh is generated successfully. Thanks a lot!
