(Regularized) Driven Cavity (I) at low Reynolds number with interior square

(Regularized) Driven Cavity calculation in a square of height and width 3, starting from rest. We only prescribe inhomogeneous boundary data at the top. For the underlying Reynolds number, Re=250, the observed flow gets steady. 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'.
