ziran2019

Visco-elasto-plasticity and fracture simulator with the material point method (MPM) -- the reference implementation of SIGGRAPH 2019 technical paper Silly Rubber and CD-MPM.

HOT

Hierarchical Optimization Time Integration (HOT) for efficient implicit timestepping of the material point method (MPM)

LETO

LETO is a new hybrid Lagrangian-Eulerian method for topology optimization. It transfers density information from movable Lagrangian carriers to a fixed set of Eulerian quadratures and solves force equilibrium with MPM. With carrier particles as design variables, LETO reparameterizes the Eulerian solution space in a Lagrangian view.

DOT

Decomposed Optimization Time Integration (DOT) is a domain-decomposed optimization method for fast, reliable simulation of deformation dynamics. DOT efficiently converges with frame-rate time-steps across a wide range of extreme conditions.

TwoFieldMPM

Two-field MPM implementation based on Damage-field gradient Partitioned MPM. Developed for comparing single-field and two-field MPMs on a variety of fracture mechanics benchmark problems in "Evaluating Material Point Methods on Problems Involving Free Surfaces and Strong Gradients".
