An overlapping grids approach for moving bodies problems

摘要

A new approach for moving grids problems in the frameworkrnof chimera methods will be described. The central issue of thernmethod is a very eu000ecient transfer of information between interpolationrn(chimera) points. This adds only a minimal overheadrnon the global computational time. As an application, the rowrnaround a 2D cylinder moving with prescribed motion will be analyzed.
