MUSEN: An open-source framework for GPU-accelerated DEM simulations

Abstract

The conceptual design, implementation aspects and main features of an open-source DEM simulation framework MUSEN have been described. MUSEN has been developed for efficient calculations that can be performed on personal computers equipped with general-purpose graphics processing units (GPUs). A very intuitive graphical user interface significantly simplifies usage of the system and reduces learning time. It makes this framework an ideal software tool for educational purposes and for solution of classical problems of solids process engineering. Users without significant experience can easily specify initial scenes, perform simulations and analyse results. In the same time, the modular-based structure of the system allows its extension with new components, calculation algorithms or contact models.
