Detailed Description

Bookkeeping for vtkUnstructuredGrid.

A low-level backend adaptor for converting OpenFOAM volume meshes/fields to VTK internal representation. The output is a single piece vtkUnstructuredGrid dataset. Multiblock composition is done by the caller.

Note
This was originally part of the catalystFvMesh function object backend, which was prototyped in the ParaView reader module. This adaptor unifies many common elements of both.
