Finite volume flow simulations on arbitrary domains

We present a novel method for solving the incompressible Navier–Stokes equations that more accurately handles arbitrary boundary conditions and sharp geometric features in the fluid domain. It uses a space filling tetrahedral mesh, which can be created using many well-known methods, to represent the fluid domain. Examples of the method’s strengths are illustrated by free surface fluid simulations and smoke simulations of flows around objects with complex geometry.
