(340ap) Pygran-Sim: An Interoperability Tool for Running DEM Simulation

Research Interests: Computational Particle Mechanics, Molecular Modeling, Reaction-transport kinetics, Software Engineering, Multiscale Methods

PyGranSim is an open-source interoperability tool designed for running Discrete Element Method (DEM) simulation. The tool provides users with an interface that can run DEM with a variety of open-source codes, thus enabling a higher level of abstraction. PyGranSim provides an intuitive syntax based on the python programming language for running complex workflows in a manner that does not require deep expertise of the underlying DEM code. The main features of PyGranSim are:

• Single python interface for running multiple DEM codes
• Parallel “multiple parameter, single script” simulation for parametrization and sensitivity analysis
• Post-processing coupled particle-mesh DEM simulation with the VTK library
• Support for high-performance distributed computing
