Patrick,
Try updating to the latest version of paraview. There have been changes to paraview that were reflected to the Sparta post processing python scripts.

Hi,

I have an issue with grid2paraview.py

If I create a grid file with:

dimension 3
create_box 0 1 0 1 0 1
create_grid 10 10 10
write_grid grid

and a grid description file mir.txt:
dimension 3
create_box 0 1 0 1 0 1
read_grid grid

then
pvpython ${SPARTA_DIR}/tools/paraview/grid2paraview.py ${CASE_DIR}/mir.txt paraview_grid

gives the following error:

Traceback (most recent call last):
  File "/home/pst/sparta-20Nov20/tools/paraview/grid2paraview.py", line 1290, in <module>
    find_chunking(chunking, grid_desc, args)
  File "/home/pst/sparta-20Nov20/tools/paraview/grid2paraview.py", line 78, in find_chunking
    Cx = grid_desc["create_grid"][1]["Cx"]
KeyError: 'create_grid'

If I use create_grid instead of read_grid in the grid description file, then it works:
dimension 3
create_box 0 1 0 1 0 1
create_grid 10 10 10

This is on Ubuntu 20.04, with paraview 5.6.0, sparta-20Nov20.

Is this a bug or am I doing something stupid here?
Thanks for any suggestions.

Patrick
