LIGGGHTS

LIGGGHTS-PFM is a Discrete Element Method simulation package maintained for particulate flow modeling. It is based on the LIGGGHTS family and is intended for simulating granular materials, particles, powders, and bulk solids. The project supports Linux installation workflows and is often used alongside CFDEM-style coupling setups. It is useful for researchers and engineers studying particle mechanics, contact behavior, flow through equipment, and industrial bulk handling. The software focuses on particle-level simulation rather than continuum-only descriptions, making it suitable when individual particle contacts and collisions matter. Its main value is giving particulate-flow users an open DEM codebase for building, running, and extending granular simulations.
