Thanks for the update.

Do you know when approximately ParaView 5.12 will be out? It was supposed to arrive this spring if I am not mistaken.

There is also a filter to convert the vtkUnstructuredGrid meshes produced by the IOSS reader into vtkCellGrid objects that properly represent the DG fields present in the file on top of the CG geometry.

Will this filter

  • be able to work with ParaView Catalyst as well?
  • be able to work in-memory (so not reading from a file but giving it a vtkUnstructuredGrid object and getting back a vtkCellGrid object)?
  • have a Python wrapper?

Did I understand correctly that the new dataset type vtkCellGrid can contain all the previous cell types (including vtkLagrange) in addition to user-defined cell types for DG, etc. elements?
Are you sure that eventually the filters (such as isocontouring, slicing, etc.) can be implemented for vtkCellGrid? I mean, there are so many exotic element types (and their numbers will grow in the future). Or will you provide an interface so that the user can implement for example the slicing of a custom cell type in vtkCellGrid?
