ArtraCFD A Computational Fluid Dynamics Solver

By Huangrui Mo

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
