PFC (Particle Flow Code) is a general purpose, distinct-element modeling (DEM) framework that is available as two- and three-dimensional programs (PFC2D and PFC3D, respectively). PFC Suite includes both PFC2D and PFC3D. PFC2D can also be purchased separately.
PFC models synthetic materials composed of an assembly of variably-sized rigid particles that interact at contacts to represent both granular and solid materials. PFC models simulate the independent movement (translation and rotation) and interaction of many rigid particles that may interact at contacts based on an internal force and moment.
Particle shapes can include disks in 2D, or spheres in 3D, rigidly connected “clumps” of disks in 2D, or spheres in 3D, and convex polygons in 2D or polyhedra in 3D. Contact mechanics obey particle-interaction laws that update internal forces and moments. PFC includes twelve built-in contact models with the facility to add custom C++ User-Defined Contact Models (UDMs).
