2D hydrodynamical simulations of dynamical shear

2D (equatorial plane) hydrodynamical simulations of dynamical shear. Panels show evolution of mean molecular weight (Abar, left) and Richardson number value (if Ri<1/4, then zone is unstable, right). The movie shows the dynamical shear instability developing after about 2000 seconds and its impact on Abar. The impact on the angular velocity (Omega) profile is similar.
