Hello everybody,

I am trying to convert a fluent mesh into openfoam format. It works fine for simple geometries as a cylinder.

However when I try to convert a axisymmetric wedge mesh (one 3D-Layer of hexas/prisms) I get the following error:

Any help would be appreciated!

I believe, that I have found the solution to the problem, which I would like to share:

The problem was, that in the mesh, which I generated using ICEM, some vertices were set to be periodic (Blocking -> Edit Block -> Periodic Vertices). After removing the periodicity of the vertices I was able to convert the mesh.
