Cgsm simulation

Diffraction of a p-wave shock by a circular cavity (velocity) showing the boundaries of the adaptive grids.

Cgsm: A Solver for the Elastic Wave Equation

  1. time dependent linear elasticity in 2D and 3D.
  2. fast and memory efficient.
  3. dynamic adaptive mesh refinement.
  4. second-order accurate upwind Godunov scheme for the first-order-system.
  5. second-order accurate conservative finite difference scheme for the second-order system.
  6. large strain nonlinear models (SVK, neo-Hookean) under development.
