Vorticity - Mixing Layer

The simulation considers a temporal developing mixing layer. The
initial horizontal velocity has a hyperbolic-tangent profile.
From linear stability analysis the mixing layer is known to be invisicidly unstable. A perturbation
leads to the formation of vortices by KelvinHelmholtz instability. KelvinHelmholtz instability leads to the
development of vortices which in a later stage roll-up and merge.
