XPS, or eXtended Particle Simulations, is a state-of-the-art Discrete Element Method simulation software developed by RCPE and distributed globally by InSilicoTrials for high-fidelity particle-based process simulation. Designed specifically for pharmaceutical applications, XPS accurately predicts powder and granular behavior, helping teams better understand, predict, and control pharmaceutical unit operations. It relies on advanced contact models to describe the flow behavior of granular materials and uses massively parallel algorithms optimized for modern GPUs to accelerate simulations, including simulations with up to 100 million particles. XPS helps pharmaceutical engineers assess process configurations in unprecedented detail, explore decision space virtually, reduce costly and time-consuming physical experiments, and support data-driven process development.

LIGGGHTS is an open source Discrete Element Method particle simulation tool for modeling particulate materials, with a focus on industrial granular and granular heat-transfer simulations. LIGGGHTS stands for “LAMMPS improved for general granular and granular heat transfer simulations,” and it builds on the LAMMPS molecular dynamics platform to extend DEM capabilities toward practical industrial applications. It can be used to simulate systems where material behavior emerges from the motion, collision, friction, cohesion, heat transfer, and interaction of individual particles. It is suitable for analyzing powders, grains, bulk solids, particulate flows, packed beds, conveying systems, mixing processes, hopper discharge, material handling, and other granular systems where particle-scale behavior matters. LIGGGHTS is currently used by research institutions and companies worldwide for the simulation of particulate materials, especially where open source flexibility.
