Vorticity field in Kelvin Helmholtz simulation

The vorticity field of a Kelvin-Helmholtz simulation for a viscid fluid obeying the Navier-Stokes equation. The color scaled is saturated conveniently to able to observe the forming structures, which increase size as time passes by. The spectral methods fails at some point in the end of the video. This was made and plotted in MatLab. Coding and video: Vítor Sudbrack (IMPA, 2018).
