Material point method The material point method (MPM) is a numerical technique used to simulate the behavior of solids, liquids, gases, and any other continuum material. In MPM a body is described by a number of small Lagrangian elements referred to as 'material points'. These material points are surrounded by a background mesh/grid that is used only to calculate gradient terms like acceleration and the deformation gradient. Unlike other mesh-based methods like the finite element method, finite volume method or finite difference method, MPM is not a mesh based method and is instead categorized as a meshless/meshfree method, examples of which are smoothed particle hydrodynamics and peridynamics. Despite the presence of a background mesh, MPM does not encounter the drawbacks of mesh-bashed methods (high deformation tangling, advection errors etc.) which makes it a promising and powerful tool in computational mechanics.
