Hi.
Can someone please give me the status of support for the VTK_HIGHER_ORDER_TETRAHEDRON and VTK_HIGHER_ORDER_WEDGE cell types in Paraview.
I have an application that uses a mix of VTK_TRI_QUADRATIC_HEXAHEDRON (27 node hex)
and the 15 node tet and 21 node wedge that map to VTK_HIGHER_ORDER_TETRAHEDRON and
VTK_HIGHER_ORDER_WEDGE. I’ve verified by looking at vtkHigherOrderTetra.cxx and vtkHigherOrderWedgd.cxx that these elements are the same (in terms of node ordering and interpolants) as what I’m using. They only previous Support posts I can find that touched on
these elements was from 2012 and mentioned something about only being supported as vtkGenericDataSet meshes. I tried setting the appropriate cell types (29, 64, and 65) in a VTK legacy unstructured grid file but got errors about 3D cells not defined or something like that).
So questions.
- are the HIGHER_ORDER_TETRA and HIGHER_ORDER_WEDGE cells supported by default in
the most recent Paraview - are these only supported by the XML file format
- are they supported in unstructured grid files (ie. .vtu etc) or is this still something that must
be done with vtkGenericDataSet. If so, can someone give me a small XML example of
what the file should look like
Thanks
