Can ACTIvate/DEACtivate be used with parallel solvers?
« on: February 21, 2024, 08:04:04 AM »
Dear all,

I am trying to use the solution command ACTIvate and DEACtivate.

This works in serial run, but gives PETSC error in parallel run.

I also tried to run this in parallel mode using only 1 processor and got the following error message in the Lfile:

 *ERROR* Cannot ACTIVATE/DEACTIVTE region number   1

Does these commands only work for serial run? Or could it be that I used it incorrectly?

Note: I am using FEAP version 8.4

I think these commands only work in serial FEAP.  Using them in parallel will require redoing the graph partitioning which is a pretty complex step. 

I seems that you have a working example in serial, but just in case I have attached an example.
