Archer

OBJECTIVE: Liquid/Gaz Interface Simulations

Describe the interface motion precisely		Level Set Method

Handle jump conditions at the interface	without artificial smoothing		Ghost Fluid Method

Respect mass conservation		VOF Method

Solve incompressible Navier Stokes equations		Projection Method

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

5th order WENO schemes for advection terms
