upsupported data type and question about cell type #172

Closed x9m closed 2 years ago

x9m commented 3 years ago

Hi, I have two questions about the elephant example.

the first one is when I import the elephant volume mesh into Paraview(version 5.9). it gave me this error message:

ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\IO\Legacy\vtkDataReader.cxx, line 2025
vtkUnstructuredGridReader (0000014B4963B440): Unsupported data type: vtktypeint32

next one is when i clicked the cell type column in spreadsheetview. it showed tetrahedron and triangle at same time. but, since i did the conversion from surface to volume why is there some triangle cell type?

will it cause any problems if I pass it to a FEM solver? or should i remove the triangle somehow?

I really appreciate if someone can help me on these issues. thanks in advance.

The surface cells are not deleted.

Hi nschloe,

Thank you for your reply.

regarding to my 2nd question, do you know how to delete the surface cells?

cheers

You'll have to juggle around with the cell types a bit. Just check out cells and perhaps cell_data and cell_sets and remove the respective entries.
