particle tracking
 
Hello,

I am solving combusting flow on a linux cluster and I notice the DPM update is taking quite a while even on 8 compute nodes. I see the parallel particle tracking concurrency is only around 4%. Is there any way to improve the concurrency?

Thanks in advance RE13

Re: particle tracking
 
I am not aware of means for improving particle tracking concurrency. I am usually solving with unsteady DPM on 8 CPU and I see anywhere from 10% to 40% concurrency. In my case most of the CPU time (99.9%) is spent for DPM iterations. My domain is 2D axi and usually contains 500,000 to 1,000,000 particles.
