Open-source Python package generates complex particle shapes for DEM simulations, enabling enhanced modeling.
multisphere is an open-source Python package for generating multi-sphere representations of complex particles for use in DEM simulations. It reconstructs triangulated surface meshes and voxelized volumes as sets of intersecting spheres and provides tools for evaluation, visualization, and export. The code implements the reconstruction method presented in Buchele et al. (2026) [1].
