[Commercial meshers] fluentMeshToFoam with Hybrid Mesh

-mAx- · May 6, 2009, 09:05

Hi,
I'm doing some tests between OpenFOAM and Fluent.
I have an hybrid mesh generated with gambit (Tetra and Hexa)
The Mesh conversion is ok, solving also ok.
When I import the result in Paraview, and when I do a Slice, I saw that the core of the hexa-domain is full of tetra.

I go back to OF, I do a checkMesh, and it returns that I have Hexaeders.
So where come those tetra from? (Paraview, VTK conversion)

Thats a paraview issue. Paraview always triangulates cutting planes also for non-tetra meshes. CheckMesh is right. Enjoy.

Ok, Thanks.
I confirmed nevertheless that it's not an OpenFOAM issue, because the mesh size computed from OF matches the one from Gambit.
