World's Largest Simulation of Supersonic, Compressible Turbulence

Astrophysicists achieve world's largest simulation of supersonic, compressible turbulence with a numerical grid resolution of 40963 points on HPC-System SuperMUC

To advance the so far limited knowledge of density probability distribution function and the power spectrum of compressible, supersonic turbulence, a team of astrophysicists compared hydrodynamic models with numerical resolutions of 2563–40963 mesh points and with two distinct driving mechanisms, solenoidal (divergence-free) driving and compressive (curl-free) driving. By doing so, the scientists ran the world's largest simulation of supersonic turbulence on GCS supercomputers.
