Reflective cells
Setting the vector \(\vec v_g\) in a ghost cell as \(\vec v_g=-\vec v\), with \(\vec v\) being the value in the adjacent real cell, yields \(\vec 0\) 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!
