We have developed approximate Riemarm solvers for ideal MHD equations based on a relaxation approach in[4],[5].These lead to entropy consistent solutions with good properties like guaranteed positive density.We describe the extension to higher order and multiple space dimensions.Finally we show our implementation of all this into the astrophysics code FLASH. |
