ADAPTIVE MESH REFINEMENT METHODS FOR 3-DIMENSIONAL INVISCID FLOW PROBLEMS

The local grid refinement technique is incorporated into a finite volu me program that solves the three-dimensional compressible Euler equati ons. The underlying idea is to improve the solution accuracy in domain s of dominating physical flow features, thus avoiding a global fine me sh to resolve most of the smooth how. An unstructured data system is i ntroduced to manage point enrichment on multiple refinement levels for structured meshes of hexahedral cells. Grid adaption is utilized to c luster points automatically in domains of interest. The multi-block fo rmulation permits the application of the refinement method to various external how configurations.
