Simulation speed increase

Dear friends,
I am running a TFM simulation (52000 cells) mesh size for time 15 sec where the time step size is 0.001, but the simulation is too slow even for a 1-sec simulation it takes 12 hours. could you tell me how can i boost the simulation speed, if I can use more cores then we can increase the speed. please let me know where I set the core size.

To use multiple cores on a single host, you need to build an SMP solver. See the section in the MFiX manual about building custom solvers.

To run on a cluster, you need a DMP solver. This is not supported for Windows, only Linux.
