I have a question regarding to a free CFD code NaSt3DGP. It uses rectangular cells. How about the cells at the wall boundary? Wall geometry may not always align with the grids. How does NaSt3DGP handle this?

A cell is either a "fluid" or a wall/boundary. Therefore, the model only approximates the geometry with a stepwise approximation. If the cells are small enough relative to the geometry change, it can be quite close.
