(Regularized) Driven Cavity (III) at medium Reynolds number with interior square

(Regularized) Driven Cavity calculation in a rectangle of height 3 and width 3 with the interior square. We only prescribe inhomogeneous boundary data at the top and at the bottom. For the underlying Reynolds number, 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'.
