Product Features
The Material Point Method (MPM) integrates the benefits of Lagrangian and Eulerian descriptions, eliminating the need for neighboring particle search and preventing mesh distortion. It is convenient to carry out seamless coupling with grid-based algorithms such as the Finite Element Method (FEM) and the Finite Difference Method (FDM), enabling efficient and high-precision solutions for complex multi-physics problems within a unify framework.
