How to convert Corner-grid format to OpenFOAM mesh
 

Hello all,

So, I have to convert a corner grid to OpenFOAM mesh. The big problem is that the grid allows for two adjacent cells to share a "portion of a face" but the mesh classes in OpenFOAM (fvMesh in particular) doesn't like this.

Does anyone know a quick way to convert it? Provided that there is some C library which, apparently, can read in the grid; which means I can easily retrieve the points cloud and their connectivity (to some extent).

This particularly leads to the ability of writing an invalid "blockMeshDict" where some cells are described like this:

But I'm not sure about where to go from there :rolleyes:


Note that trying to extract the surface mesh from the grid and re-meshing it with tools like "cfMesh" didn't work, obviously because of the same issue ::(

"Bounding box (0 0 -20) (7000 7000 0)"

Thanks in advance.
