anyone using NaSt3DGP?
 
Hi,

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?

Thanks

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.
