For blunt body, the ghost cell boundary condition is easy. But for a geometry with sharp angle, how to implement the ghost cell boundary condition?
To find the ghost point, the normal vector of the wall is needed. But in the region near the sharp angle, how can I find the normal vector for a vertex of a sharp angle?? |
