# Flow around a sphere

A snapshot of a recent computation with the unstructured DGSEM code Flexi of the flow around a sphere at RE=1000 and Ma=0.3. The computation was run on the new Cray XE6 “Hermit” at HLRS on 4096 cores. The picture below shows the laminar separation, the vortex street and the transition in the wake ($\Lambda_2$ criterion).
