This is a short summary of how to install LIGGGHTS on Linux. A more comprehensive guide can be found in the documentation.
sudo apt-get install build-essential cmake openmpi-bin libopenmpi-dev python-devWe recommend installing LIGGGHTS to a directory named CFDEM, especially when used with CFDEMcoupling.
cd
mkdir -p CFDEM
