Initial and boundary conditions together with some adaptive calculations for this frequenetly studied test case are available under ClawpackEuler2dRamp. Apparently the solution should be rotational invariant and therefore makes a perfect test for the ghost-fluid method in realistic cases. Displayed are isolines for the density at the same values.

Especially the tangentially developing vortex at the end of the slip line appears to be more diffused. This is in agreement with the conlusions and recommendations regarding the ghost-fluid method.
