How big a PFC3D model can you run on a modern PC - assuming spherical particles? More than a million?
Though computers have gotten more\faster memory, the CPU speeds haven’t increased much nor have the CPU caches. PFC3D can simulate somewhere in the low millions of spherical particles reasonably on a single, modern PC.
Itasca is currently working on an MPI algorithm that we expect will push this into the 10’s of millions of spherical particles by solving a single model across several computers. The development of web licenses for cloud computing plus a Linux OS version, which are currently available, is part of our MPI development process.
