Multiple solutions in lid-driven cavity flows II. Anti-parallel wall motion

Two-dimensional solutions for the two-sided lid-driven cavity problem are c alculated in a wide parameter range using finite volumes. By a tracking met hod we find multiple flow states which either preserve or break the symmetr y of the governing equations when the boundary conditions are symmetric. Al l solution have been traced for non-symmetric boundary conditions to explor e the connection of the different solution branches. The solution manifold is illustrated by two- and three-dimensional cuts through the catastrophe s pace.
