T. Schonfeld, ADAPTIVE MESH REFINEMENT METHODS FOR 3-DIMENSIONAL INVISCID FLOW PROBLEMS, International journal of computational fluid dynamics, 4(3-4), 1995, pp. 363-391
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.
