AI 中文摘要
GEMSS（多球体形状生成器）采用最新发布的MSS算法，将三维表面网格或体素网格转换为颗粒的多球体表示，计算离散元法（DEM）和一般多体动力学模拟所需的关键物理属性，包括颗粒体积、质心、惯性主轴与主矩。作为仅头文件的C++库，GEMSS易于集成到DEM和分子动力学框架中，已集成至MercuryDPM，可在模拟循环内实时生成多球体颗粒。
英文摘要
GEMSS (GEnerator of Multi-Sphere Shapes) converts 3D surface meshes or voxel grids into multi-sphere representations of granular particles using the recently published MSS algorithm. It computes key physical properties required for discrete element method (DEM) and general multibody dynamics simulations, including particle volume, center of mass, and principal moments and axes of inertia. Implemented as a header-only C++ library, GEMSS is easily integrated into DEM and molecular dynamics frameworks. The library has been integrated into MercuryDPM, which enables on-the-fly generation of multi-sphere particles directly within the simulation loop.
