J un 2 01 4 Achievable E ffi ciency of Numerical Methods for Simulations of Solar Surface Convection

We investigate the achievable e fficiency of both the time and the space discretisation methods used in Antares. We show that the fifth order variant of WENO combined with a second order Runge –Kutta scheme is not only more accurate than standard first an d second order schemes, but also more e ffici nt taking the computation time into account. Then, we cal… CONTINUE READING
