Unable to perform clipping or cell selection for unstructured meshes loaded by a vtkPythonAlgorithm-based reader

Using the meshio library, I recently created a vtkPythonAlgorithm-based plugin allowing reading many additional mesh formats (GMSH, Abaqus, MED, ...), see meshioReader but also #19411.

Following PythonAlgorithmExamples.py, I essentially implemented a RequestData method that generates a vtkUnstructuredGrid output.

However, it seems that cell operations can not be properly performed on the mesh.

  1. Clipping or plotting over line leads to ParaView crash
  2. Cell selection is erroneous

What am I missing? Do I need to implement more methods for those cell operations to work. Thanks.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
