Abstract : This paper discusses the issues which arise when combining multigrid strategies with adaptive meshing techniques for solving steady-state problems on unstructured meshes. A basic strategy is described and demonstrated by solving several inviscid and viscous flow cases. Potential inefficiencies in this basic strategy are exposed and various alternate approaches are discussed some of which are demonstrated with an example. Although each particular approach exhibits certain advantages, all methods have particular drawbacks, and the formulation of a completely optimal strategy is considered to be an open problem.
