Hello

I am new to CFD and openFoam in general and having problems converting my mesh.

It is a fairly simple model of 2D flow around a cylinder, I have two cases one laminar and one turbulent however I get the same error with both when I run the command ideasUnvToFoam and get the following :

I have searched and found a similar problem being fixed with a patch but this didn't seem to work for me. Could anyone advise please?

Thanks

Hi Matt. I have the same problem.

my geometry and mesh groups were created in salome-meca and seem to be ok. no duplicate faces or extra edges. when I use ideasUnvToFoam,terminal issues warning:

Sorting boundary faces according to group (patch)
0: inlet is patch
1: outlet is patch
2: cylinder is faceZone
3: top is patch
4: bottom is patch

Constructing mesh with non-default patches of size:
inlet 450
outlet 450
top 450
bottom 450
front 5973

how did you manage to fix it? what do you mean by "put top_bottom" twice??

Did anybody find a way around it ?
I am only 4 different face groups and I am getting the same error ..
