Abstract

An implicit muItigrid-driven algorithm for two-dimensional incompressible laminar viscous flows is coupled with a mesh adaptation method to better capture the important features of the flow for time dependent problems. Time dependent calculations are performed implicitly by regarding each time step as a steady-state problem in pseudotime. The method of artificial compressibility is used to solve the flow equations. An adaptation method performs local mesh refinement using an incremental Delaunay algorithm and mesh coarsening by means of an edge collapse. The method is validated by comparison with experimental results of low Reynolds number flow over a shedding circular cylinder.
