Re: [sparta-users] [EXTERNAL] Issue with grid2paraview.py

[<pat...@me...>]

Hi Michail,

 

It turned out that two steps were needed to solve this:

1. Using the right paraview version: 5.7.0 (which is actually the version bundled with Ubuntu 20.04. I was inadvertently still using 5.6.0)

2. Using the latest grid2paraview.py from GitHub (grid2paraview.py from the sparta-20Nov20 release does not work).

 

Thanks for your help!

 

Patrick

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
