Class
    Foam::vtkPVblockMesh
 
Description
    The backend for the vtkPVblockMeshReader reader module -
    providing a paraview reader interface for OpenFOAM blockMesh.
 
    The block reader module can assist when creating a blockMeshDict
    for use with the blockMesh utility. As well as blocks, it can be
    used to visualize edges,corners and patch names.
 
    There is no native VTK equivalent for this functionality.
