Abstract

We propose a new version of HLLEM approximate Riemann solver where local antidiffusive coefficients are calculated to have robustness and accuracy in the obtained scheme. We introduce the concept of Riemann-stability, property satisfied by our method, which guarantees its good behaviour in known difficult situations. Numerical results are presented to demonstrate the efficiency of our approach.
