The numerical study of multi-phase / multi-component systems requires addressing the problem of dealing with complicated geometries (e.g. an interface), and discontinuous solutions (e.g. pressure in two-phase Navier-Stokes). In this talk I will present a method for representing and evolving surfaces (open of closed) and a method for solving Poisson’s equation with internal jump conditions. Both methods assume a regular Cartesian grid, have optimally local stencils, and have arbitrary accuracy. Throughout the talk I will show simulations of physical systems involving fluids and solids.
