Class
    Foam::fvMesh
 
Description
    Mesh data needed to do the Finite Volume discretisation.
 
    NOTE ON USAGE:
    fvMesh contains all the topological and geometric information
    related to the mesh.  It is also responsible for keeping the data
    up-to-date.  This is done by deleting the cell volume, face area,
    cell/face centre, addressing and other derived information as
    required and recalculating it as necessary.  The fvMesh therefore
    reserves the right to delete the derived information upon every
    topological (mesh refinement/morphing) or geometric change (mesh
    motion).  It is therefore unsafe to keep local references to the
    derived data outside of the time loop.
