| Penalization methods are an efficient alternative to explicitly impose boundary conditions but their accuracy is generally of first order. In this work we propose to combine the easiness of penalization techniques with the precision of unstructured anisotropic mesh adaptation. Level sets are used to describe the geometry so that geometrical and topological changes due to physics are straight forward to follow. Navier-Stokes simulations are performed and a new way to impose a slipping wall boundary condition is proposed. |
