Parallel, block-adaptive MHD simulations for solar coronal dynamics.
The SAC and SMAUG codes are based on the Versatile Advection Code we heard from one of the authors of the code about MPI-AMRVAC. This code is an advance on VAC,  the parallel scaling of the code exhibits weak scaling up to 30000 processors allowing to explo...
