Detailed Description

A deep-copy description of an OpenFOAM volume mesh in data structures suitable for VTK UnstructuredGrid, including the possibility of decomposing polyhedral cells into primitive cell types.

Knowledge of the vtkUnstructuredGrid and the corresponding .vtu xml file-format aids in understanding this class. The class can be used for the VTK xml format, legacy format, as well as a VTK internal representation. The internal representation is somewhat related to the xml format, but not entirely.
