A Material Point Method solver developed with JAX

This code is still in pre-alpha, i.e., all models may not be feature-complete.

Current features

Basic shape functions (linear, cubic) Solvers (USL, APIC) Materials ( Drucker Prager, Linear isotropic Elastic, Modified Cam Clay, Newtonian Fluid, $\mu (I)$ rheology) Forces (Rigid body contact, gravity, slip and no slip boundaries)

Installation instructions

• Install uv here
• Clone repository git clone [email protected]:GrainLearning/HydraxMPM.git && cd HydraxMPM
• Install dependencies uv sync
• Run an example, e.g., uv run examples/dambreak/dambreak.py. Output is found in the ./examples/dambreak/ directory.
