Incremental Potential Contact (IPC) is for robust and accurate time stepping of nonlinear elastodynamics. IPC guarantees intersection- and inversion-free trajectories regardless of materials, time-step sizes, velocities, or deformation severity.

A curated collection of Python examples for optimization-based solid simulation, emphasizing algorithmic convergence, penetration-free, and inversion-free conditions, designed for readability and understanding.

A simple Matlab implementation for 1D finite element methods for different physical phenomena: Heat transfer (linear/non-linear, steady-state/transient), wave equation (elastodynamics), and Coupled thermo-mechanics.

A real-time soft body simulation framework

PanNDE: A Modular Architecture for High-Performance NDE Simulation

Solid Wave Simulation (swSim) is software that solves heterogeneous, anisotropic elastodynamic equations for ultrasonic NDE simulation. A time-explicit staggered grid finite difference (FD) scheme is employed and solved on graphics processing units (GPUs). Parallelism via the Message Passing Interface (MPI) allows for deployment on a cluster, or…
