Dear Prajjwal,
Could you try the latest master branch? This issue with copying is solved
there.
Regarding your motivation, to run several fem simulations simultaneously.
It works a bit different. Open mp parallelization of getfem
primarily relates to parallel assembly for stiffness matrices and RHSs for
a single simulation (not even the solver).
If you really want to launch multiple independent simulations in parallel
you don't need OpenMP.
You can launch them one by one through a command line or a script.
Best regards,
Andriy
