We investigate the performance of the multiresolution method. The method was recently proposed as a way to speed up computations of compressible flows. The method is based on truncating wavelet coefficients. The method showed good performance on one-dimensional test problems. We implement the method

We present multiresolution (MR) schemes for the efficient numerical solution of the one-dimensional system of the reactive Euler equations, which has possibly stiff source terms. The original version of the method was developed by A. Harten (1995, Comm. Pure Appl. Math. 48(12), 1305) for homogeneous
The work presented in this paper shows that the mixed-type scheme of Murman and Cole, originally developed for a scalar equation, can be extended to systems of conservation laws. A characteristic scheme for the equations of gas dynamics is introduced that has a close connection to a four operator sc
