# PhasicFlow: src/Interaction/grainInteraction/boundaries/periodicBoundaryGrainInteraction/periodicBoundaryGrainInteraction.cpp Source File
PhasicFlow is an open-source parallel DEM (discrete element method) package for simulating granular flow. It is developed in C++ and can be exectued on both GPU (like CUDA) and CPU.
