There are a number of problems in computational MHD which require specialised, custom schemes. The most important of these for Warwick's research programme is the ability to resolve MHD shocks in low plasma beta. This often precludes the standard Riemann solver based approach as such schemes give inaccurate measures of the plasma temperature in low beta. This problem can be avoided by the use of staggered grid Lagrangian remap codes which also have the advantage of being easier to modify to include extra physics. Devolopment of these algorythms, including implementations of open boundaries and adaptive mesh refinement, is an active area of computational research at Warwick.
