Hi Foamers,

I have a problem with Salome/OpenFoam.

There is a viscous layer in my current mesh and it is generating a problem once I export it to UNV to use it in OpenFoam later: the viscous layer is generating a face which is identified when I export to OpenFoam and create a defaultFace I cannot get rid off.

(I first had this defaultFace poping, I went on paraFoam to see it and it was a face 3mm above my actual wall corresponding to the last viscous layer...)

Does anyone has an idea on how to handle this problem? It never appeared before... Thanks :')

EDIT: The ideasUnvToFoam command is telling me at the end:

FOAM Warning: [...] Found 31920 undefined faces in mesh; adding to default patch.

The thing is I cannot find those faces in Salome.

EDIT2: checkMesh is telling me there are two regions in my mesh which is not normal. I should probably try to merge these two regions into one. Somehow...

EDIT3: Everything is fine as long as I remove the viscous layers.

"Solved" my problem by computing the mesh again... It was a bug I guess.

Well, I changed some parameters in my mesh to improve my computation but the problem is coming back and I cannot get ride off it by simply computing the mesh again and again... Any idea to fix my problem properly?

Hi,

I have exactly the same problem. I don´t know how to solve that. Could you find a way to handle it in the meantime?

@NoradFirst2 or @cristopf were you able to solve this?
