My simulation runs in serial, but when I build a solver to run in parallel using SMP, I face the following error (except using one core). It does not depend on the number of cores that I use. Actually, the error occurs when it want to go to the next time step after converging in the current one.
What can I do?
The interesting point is that I have run it in 3 different machines using SMP and it printed the mentioned error. Only on my old laptop with only 2 local cores, it ran using SMP.
