You will get better results if you refine the mesh and a better order with Bouzidi’s boundary conditions. We are currently working on Bouzidi’s boundary conditions.rnrnMathias
rnrnWell, I did not know that you are still using wet bounce back, Mathias. As I told you in Changchun, it should be dry bouceback, or half-way bounceback, proved 2nd order accurate by Ladd el (if I am right). The accuracy depends on how you draw the geometry.
