Numerical Experiments with Point Value Multiresolution for 2D Compressible Flows
G. Chiavassa and R. Donat
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.
