Mesh refinement in parallel

KrisT · August 21, 2009, 08:07

Hi,

I have done simulations of a propagating shock with dynamic mesh refinement (using rhoCentralFoam).

This all works. However, when running parallel I get issues with load balancing. If the shock happens to be in a domain belonging to a few of the processor these processors get to do all the extra work while the remaining processors sit idle for a large fraction of time - which is obviously ineffective.

Is there a way to handle this?

Regards,

/k
