io.import_foam_mesh

[fbob]

I would like to use io.import_foam_mesh to read the tutorial mesh with io.import_foam_mesh('./buoyantCavity') but got the following issue:

TypeError                                 Traceback (most recent call last)

TypeError: 'NoneType' object is not iterable

The commits 7b86e9b and 12f3523 should fix the error msg. At the moment import_foam_mesh just reads the 'faces', 'points', 'owner', 'neighbour' files and returns a DataFrame. Next step should be a function that generates 'cellCentres' from that DataFrame.

Commits 9c6bcbb and 2f16236 introduces Owls.mesh.Mesh you can create an Mesh object and compute face and cell centres. That already allows us to filter eulerian fields by spatial criteria. However so far this is only experimental and results for tetrahedra or skewed meshes are not correct atm. Next step will be sample lines and then parallel processing.
