Abstract

Local refinements procedures aim at accurate flow solutions with a reduced impact on system resources. Additionally, the aim of the POPINDA project was the efficient implementation of a parallel, self-adaptive local refinement procedure for three-dimensional applications. The adaptation of the grids is thereby based on the insertion of grid points in regions with high discretization errors. In parallel, this results in additional communication tasks and the necessity to dynamically balance the load on the requested nodes. The local refinement procedure has been integrated in the existing multigrid algorithm of the FLOWer code, maintaining the numerical efficiency as the primary effort. In the POPINDA project, the complete procedure has been implemented and some first tests show the usefulness and perspective of the procedure.
