Taylor-Green vortex sheet at Re=2000, pFEM
Simulation of the Taylor-Green vortex sheet at Re=2000. Seems to become unstable at about t=15.
pFEM - like method, Co=0.13, 160 x 160 nodes, Dx = 0.0125, times from 0 to about 25. Left: pressure. Right: vorticity (to be more precise: a field that's given the vorticity initial value, and is then evolved).
