Mesh conversion from Ansys ICEM

fabian_korn · December 14, 2009, 05:05

Hi to all,

i am trying to use a mesh generated with Ansys ICEM to convert to an OF 1.6 mesh. I exported the mesh in ICEM as a fluent_V6 mesh.

Then i tried to use fluentMeshtoFoam to read this mesh, but it did not work. I got the following massage:

I don't have Fluent format myself, but I think that fluent3DMeshToFoam might be what you want to be using.

I already tried fluent3DMeshToFoam and it did not even started a conversion, but thank you for the guess.

Hi to everybody again,

i managed to convert a very simple net. But i still have a problem. The problem is an easy box with a cylindrical hole inside. When i watch this area with paraFoam it appears that my cylindrical hole is rectangular. And the boundaries are converted incorrectly.

Does anybody has a guess about this problem?

Thanks a lot
