[Paraview] non-interactive viz on cluster

[Kharche, Sanjay]

Hi David


Your suggestion of a loop within the python script did not work. I make 5k to 10k pngs,

and the process was killed at a few hundred.


Since my process is serial at the moment, my solution is that I take an input from a bash

script:


import system


i = system(argv[1])


(or something similar). And my python is for 1 i that is read in.


That gives me a consistent predictable (in terms of time it takes)

working of my visualisation.


cheers

Sanjay
