How to improve the slow running simulation

#1

Dear developers,

I am running the simulation using PIC method, but the simulation runs extremely slow, i wonder is there any method apart from reducing mesh number that can help speed up the simulation?

I am using a workstation with 64 cores to do the simulation. Thanks!

Your best bet is to coarsen the mesh or run with more cores. Look at your convergence history and time step, if you hit the max time step, you can try to increase it, say to DT_MAX=1E-3. You can also set the residual normalization factor norm_g=0 to see if this helps.
