CoSim:一个用于多过程、多相态及多尺度分析的耦合模拟器
CoSim:A Coupling Simulator for Multi-process,Multi-phase,and Multi-scale Analysis
摘要
Abstract
Multi-process,multi-phase,and multi-scale(or"3M")phenomena are critical challenges in nature systems and industrial and engineering fields.Numerical calculation serves as an essential para-digm in modern scientific research and engineering analysis.Starting from the physical-mechanical mechanisms of"3M"and leveraging the strengths of diverse numerical methods,this study developed coupled algorithms to achieve complementary advantages among these methods.A distinctive charac-teristic of"coupling"between algorithms was formed,supported by GPU parallel acceleration to en-able large-scale,high-performance calculation analysis.This led to the development of a novel high-performance numerical calculation platform—Coupling Simulator(CoSim).Currently,the CoSim soft-ware includes solid mechanics,fluid mechanics,and couplings between different algorithms,with 16 solver modules and 1 CAE module in total.It overcame the limitations of most existing software that relied on single-algorithm approaches and struggled to simulate complex"3M"problems.Additionally,CoSim enabled coupled analyses—including continuous-discontinuous,continuum-to-fracture,fluid-solid,and micro-macro—for geotechnical and other materials throughout the entire process of"defor-mation→progressive failure→catastrophe".The software more accurately approximated complex real-world physical-mechanical behaviors,providing a powerful new-quality productivity for tackling intri-cate"3M"challenges.关键词
