I am doing my master thesis (simulation of roller compaction-pharmaceutical powder).
I have verry big problems with high number of particles (mean diameter is 120 µm).
For 1 g of powder I need 700 000 particles. That is a lot because for filling volume of roller compactor I need "rough estimation" 20 milion particles.
So for that many particles I don't have proper hardware.
In roller compactor I must meausre density in specific regions (picture "Density measure").
Any advice how to do that with 4 cores for now??? I hope that my professor will acomplished install and compile liggghts on hpc workstations with 40 or 200 cores. But this is stil to large number of particles???
And one more question about size of mesh. Two pictures is in attachment where You can se size of particle and mesh size. Is mesh size good???
