Numerical Experiments with Point Value Multiresolution for 2D Compressible Flows

G. Chiavassa and R. Donat


Abstract: Following the idea of A. Harten we present in this paper a method to reduce the execution time of simulations using High order shock capturing schemes. It is based on a point value multiresolution transform that is used to detect regions with singularities. In smooth regions the expensive numerical flux computations are replaced by a cheap polynomial interpolation of the numerical divergence. This method is applied to solve the two-dimensional compressible Euler equations for two classical configurations. The results are analyzed in terms of quality and efficiency.
