(Regularized) Driven Cavity (III) at medium Reynolds number with 2 interior squares

(Regularized) Driven Cavity calculation in a rectangle of height 3 and width 5. We only prescribe inhomogeneous boundary data at the top and bottom. For the performed 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'.
