[Technical] FvMesh

polyMesh, polyBoundaryMesh and polyPatch are generic, that is they do not presuppose any particular form of discretisation, they are the basic classes of the polyhedral mesh. fvMesh is derived from polyMesh and adds the particular data and functions related to the geometry needed for finite-volume discretisation. fvPatch is not derived from polyPatch but does hold a reference to one and also includes fuctions related to applying boundary conditions for finite-volume discretisation.

It should ;-) Both are calculated as slices of the primitiveMesh::faceCentres.

However if you are using fvc/fvm it might be wise to use fvPatch::Cf() or fvMesh::Cf() for consistency reasons.

Hi
I have read programmer guide and searched a lot! but I didn't get the exact defination and application of fvMesh and polyMesh.
Could you please explain about it?

Did you saw that the posts are almost 13 years old? It was in the beginning.
