ideasUnvToFoam problem with internal groups
3 Attachment(s)
Hello all,
I'm a beginner with OpenFoam and I'm trying to import a mesh created in Salome to OpenFoam using the format .unv and ideasUnvToFoam. I want to run a rotating mesh simulation so I need some internal groups to create the "AMI", I've made the groups in Salome (see attached screenshot) and everything is ok.
When I export this mesh to .unv format, everything works right. I've imported this .unv file int another program (and back into salome) and the groups are ok.
But when I use ideasUnvToFoam it shows
Code:

For group 4 named top trying to read 140 patch face indices.
For group 5 named bottom trying to read 140 patch face indices.
Sorting boundary faces according to group (patch)
0: inner_circle is patch
1: outer_circle is patch
2: middle_circle is cellZone
3: top is patch
4: bottom is patch
Constructing mesh with non-default patches of size:
inner_circle 11
outer_circle 21
top 140
bottom 140
Adding cell and face zones
Cell Zone middle_circle 12
End
So it makes a cell zone with the inner groups (it should do a face zone I think, but I could convert it later). But this is not the only problem, because when I run paraView and show this cell zone I found that it is not formed by the appropriate elements (see attached screenshot).
I think that there may be a problem with ideasUnvToFoam but I don't know C so I cannot understand the code to try to repair it.
Please, if someone knows what I'm doing wrong or where the problem may be, a little help would be great.
Sergio.
PS: I know that the mesh is not as fine as it must be, but this is just a test with a simple mesh to avoid uploading huge files.
I have tried it with a real mesh (400k elements) with the same problem, the internal group is not well converted.
The attached zip file is the .unv mesh file
Edit: I am using salome 7.2 and OpenFoam 2.1 |
