(Regularized) Driven Cavity (II) at medium Reynolds number (height 4, width 1 of the cavity)

(Regularized) Driven Cavity calculation in a rectangle of height 4 and width 1, starting from rest. We only prescribe inhomogeneous boundary data at the top and at the bottom. For the underlying Reynolds number, Re=20,000, the observed flow gets nonsteady. This simulation is part of a Software-Praktikum at the University of Heidelberg in 1997, with the aim to compare different Driven Cavity configurations. See the corresponding pages in the 'Virtual Album'.
