Solver configuration

Fluid-solid interaction:

  • Operator splitting

Fluid dynamics:

  • Governing equations: 3D Navier-Stokes equations (Cartesian, compressible, conservative)
  • Temporal discretization: RK2 and RK3
  • 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
