Ok, so I am still a beginner at OF trying to figure how things work out. I imported 2 meshes with varying success:

1. From HyperMesh in .cas format, then imported via fluentMeshToFoam. Importing was successful, but could not visualize w/ paraFoam, used

> foamToVtk
> paraview

Opened the 0.vtk file and it worked like a charm!

2. From Star CCM+ 8.04, I imported the 2D mesh from the back step tutorial. ccm26ToFoam worked fine and updated the files in the polyMesh folder (all but blockMesh).

Now I tried to do exactly as I did before:
1. deleted the p, U 0-files.
2. foamToVtk (so that I can use paraview)

but I received the following error(s):

So, any idea how to fix that? Thanks.

Greetings sudo,

Well, the problem is that the mesh is far from perfect, which leads to foamToVTK not be able to split a strange looking cell.
You can try using the option "-poly", which preserves the structures of polyhedral cells, without splitting/decomposing them; but I'm guessing you'll get another similar problem sooner or later, since the mesh is not perfect.

As for not being able to open the mesh with paraFoam, I won't be able to help without seeing the complete error message.

Best regards,
