Lid-driven cavity

A basic scene description file for the lid-driven cavity problem can be found in the examples directory in the subdirectory Cavity2D (this file was also used in the introductory chapter). For this calculation some parameters have to be adjusted. These benchmark results refer to the cavity flow at Re = 1000. For the convective terms, the 2nd/3rd order VONOS scheme was used. Calculations are done on a 48x48 grid and a 96x96 grid. The Poisson solver is stopped when Res$ <1e-8$.

All test computations were finished after 300 time units. The level-values for the streamfunction/vorticity are taken from [4].
