You still haven't told me the exact type (i.e., VTK class name) of
the mesh. Most probably, it is a vtkUnstructuredGrid which will not
work with the vtkGenericDataSetTessellator unless you convert it to
a vtkBridgeDataSet first -- look in VTK/GenericFiltering/Testing/Cxx
for information on the vtkBridgeDataSet classes. Your other option
(and probably the faster option) for refining the hexes is to grab
the vtkTempTessellatorFilter from ParaView/Servers/Filters and pass
it your vtkUnstructuredGrid directly (or use ParaView to run the
vtkTempTessellatorFilter on your data and save the resulting mesh).
