Hi there,

I am performing quasi-static analyses with Abaqus/Explicit, and I have encountered some problems in using domain-level parallelization.

Assume that there are 1000 shell elements in total in the model. If I use 10 CPU processors to run the model, i.e., "abaqus job=job-name cpus=10". Then the whole model would be divided into 10 domains, and each domain contain ~100 elements which is expected. However, if "viscous pressure" is applied in the model to introduce damping, note that the viscous pressure is applied to all element surfaces, then the parallelization doesn't work. The thing is: the whole model is also divided into 10 domains, but one domain contains all 1000 elements and the other domains contain 0. And the simulation takes a very long time.

What can I do to enforce the parallel computing in abaqus explicit while applying viscous pressure to damp the structures?

Thanks.
