Abstract: 

A key aspect in computational astrophysical fluid dynamics is the need to deliver higher and higher accuracy for longer and longer time integration. Modern architectures such as massively parallel computers or graphical processing units (GPU) can be leveraged to increase the spatial and time resolution of simulations. We present a new numerical scheme which combines the Spectral Difference (SD) method up to arbitrary high order with a-posteriori limiting. It delivers very accurate solutions in smooth regions of the flow, while capturing sharp discontinuities without spurious oscillations.
