[Nek5000-users] Post-Processing from avg_all files using Nek / Visit

[nek5000-users at lists.mcs.anl.gov]

Hi Hank,

Thanks. I think I can automate (with python) till I get Visit to do a line
plot. Do you know a way I can just export the data from line plot to a text
file ? I might have about 10 line plots (900 time steps) which I would like
to automate.

Regards
Shriram Jagannathan
