“…Often more than one type of reÿnement will be used. The two main approaches of h-reÿnement for unstructured meshes of triangles in two dimensions or tetrahedra in three dimensions are by the insertion of new points on the edges [14][15][16][17][18][19][20] and by insertion of new points by a Delaunay based method [6,[21][22][23][24]. The former approach o ers the advantage of being straightforward to implement.…”

SUMMARYAn implicit multigrid-driven algorithm for two-dimensional incompressible laminar viscous ows has been coupled with a solution adaptation method and a mesh movement method for boundary movement. Time-dependent calculations are performed implicitly by regarding each time step as a steady-state problem in pseudo-time. The method of artiÿcial compressibility is used to solve the ow equations. The solution mesh adaptation method performs local mesh reÿnement using an incremental Delaunay algorithm and mesh coarsening by means of edge collapse. Mesh movement is achieved by modeling the computational domain as an elastic solid and solving the equilibrium equations for the stress ÿeld. The solution adaptation method has been validated by comparison with experimental results and other computational results for low Reynolds number ow over a shedding circular cylinder. Preliminary validation of the mesh movement method has been demonstrated by a comparison with experimental results of an oscillating airfoil and with computational results for an oscillating cylinder.

The latter approach is more flexible because it allows points to be inserted anywhere rather than being constrained to insertion on an edge.…”

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.
