Flow simulation speed with dual processors.

I have a dedicated simulation computer that has dual Xeon E5-2687W v3 10-core processors (20 cores total). I have been running speed tests to get the best performance, and the fastest solve times are when I limit flow simulation to 10 cores (1 CPU). Does anyone know how to get flow simulation to effectively utilize both CPUs? I have tried opening two instances of solidworks and manually setting the affinity of both solidworks and the solvers to seperate CPUs, but they still seem to cross-over and cause the solve time to double. This is not an issue of maxing out the computer's resources because if I batch run 2 sims limited to 10 cores it is back down the half the solve time. Any ideas or suggestions would be helpful.
