The vtkhdf_vtk_cell_types module¶

This module defines named int8 parameters corresponding to VTK cell type identifiers.

These parameters are intended for use in the types argument of write_mesh.

The set of named parameters provided here is not intended to be exhaustive. In general, any VTK cell type code that is valid for UnstructuredGrid may be used in the types array; fVTKHDF does not attempt to restrict or reinterpret these codes.

The integer values are defined by VTK and are reproduced here for convenience. The authoritative definitions may be found in:

The VTKHDF file format documentation: https://docs.vtk.org/en/latest/vtk_file_formats/vtkhdf_file_format/index.html
Common/DataModel/vtkCellType.h in the VTK source tree.
