A three-dimensional test case for the density driven flow equations in porous media recently proposed by Oswald, Scheidegger and Kinzelbach is investigated numerically. It was shown in  that the results from the physical experiment can be reproduced if parameters are adjusted correctly and that a mathematical benchmark can be defined as an idealization of the physical experiment. Intensive numerical investigations were carried out, with calculations on up to 16.7 million grid points that required the efficient solution of linear systems with more than 35 million unknowns.
