Archer is a 3D incompressible Navier Stokes solver with Level Set-Ghost Fluid-VOF coupling and MPI parallelization
NUMERICS
- Cartesian mesh
- Mac grid (velocities on cell boundaries)
- WENO 5 scheme for convective terms, Adams Bashforth or RK3 or split algorithm in time
- Multigrid algorith for preconditionning Conjugate Gradient Method in Poisson equation solver
- Ghost Fluid method for variable discontinuities at the interface
- CLSVOF for mass conservation
- MPI parallelization
UNDER DEVELOPMENT
- Immersed boundaries
- Adaptive mesh refinement
- Coupling with Lagrangian solver
