CFD Online Discussion Forums - [Commercial meshers] case File with a polyhedral mesh to OpenFoam

Hallo,

I got a fluent case file with a polyhedral mesh and two cellzones is there any possibility to convert this to OpenFoam?

I tried fluentMeshToFoam and got this:

Code:

I can convert the Mesh file with fluent3DMeshToFoam, but this is tet/hex and not polyhedral and checkMesh look like this:

Code:

Create time

 



 Create polyMesh for time = 0

 



 Time = 0

If I use fluentMeshToFoam on the mesh file i got this error:

Code:

Has anyone an Idea?
