Spatial discretization: WENO3 and WENO5 (convective fluxes) + 2nd order central scheme (diffusive fluxes)
Boudary treatment: immersed boundary method

Solid dynamics:

Governing equations: Newton's second law (translation), Euler equations (rotation), multi-body contact and collision
Temporal integration: RK2
Interface description: triangulated facets with front tracking
