Open Questions

Reflective cells

Setting the vector vg in a ghost cell as vg=v, with v being the value in the adjacent real cell, yields 0 as interpolation right at the boundary. This works for plane walls. What to do in cases where a ghost cell has more than one real cell as nearest neighbor? This calls for discussion!
