Special Notice: ENERGY, DEPARTMENT OF is seeking Open Source Software: LIGGGHTS-INL for Pioneering Biomass Feedstock Handling with Advanced Particle Simulation. This software is crucial for the design and optimization of biomass feedstock handling equipment. LIGGGHTS-INL combines Discrete Element Method (DEM) simulations with real-world laboratory validations to accurately model biomass particle flow. It addresses the challenges of handling biomass materials, which have irregular and cohesive nature. The software, built on the LAMMPS molecular dynamics simulator, incorporates experimentally validated mechanistic laws and supports the numerical prediction of biomass particle behavior. It aims to enhance the efficiency and cost-effectiveness of biofuel production facilities by optimizing biomass feedstock handling processes and mitigating processing upsets such as jamming and clogging. LIGGGHTS-INL also supports bioenergy research and facilitates partnerships and innovation in bioenergy technologies.
