Hi! Is there any posibility to import a mesh generated with Gambit with "hex core"? There are some discussions about hanging nodes, and the conclusion as I red was that OpenFOAM should be able to handle such grids.
Attached, there is a small mesh as a nonworking example. If I try to import it, I get the following:
--------------------------------------
dragosm@lap08:~/OpenFOAM/dragosm-1.3/run/hangingNodes> fluentMeshToFoam ./ case hangingNodes.msh

Any chance to get the mesh in OpenFOAM?
