Using TPLOt with parallel FEAP
« on: June 23, 2020, 01:17:34 PM »
Dear Prof. R.L. Taylor,
Dear Prof. S. Govindjee,
Dear Users,

I'm currently trying to postprocess my simulation (ParFEAP version 8.5) via the TPLOt command. As mentioned in older posts I specified the nodes trough positions:

BATCh
TPLOt,,1
END
DISP,,2,1.0,1.0
REAC,,2,1.0,1.0

Doing this, I get a separate output file for each computational domain. My actual problem is, that every output file contains values so — without identifying the correct output by comparing the spezified position with the nodes belonging to each domain in a separate script — I can't determine the "correct" output easily.

Is there a mistake in my input file or a known workaround to deal with this issue?

Kind regards

Prof. S. Govindjee

Assembling parallel output can get complicated and we often do it with customized scripts (awk, python, etc.).

One things that can help is using global lists (glist).  You define a GLIST using global node numbers.  Then issue commands like
disp,list,<list_num>
This will write the value to the outfiles but only on the processor with the global nodes defined in the list.

See Appendix B of the user manual.  global lists only work for some commands and there are other limitations as indicated in the manual.
If you want to do something in particular and the code will not let you, please make a post to the Wishlist.
