Corner B.C.
Hi
I am trying to simulate supersonic flow past a forward facing step using Riemann solvers at cell interfaces (i+1/2, j+1/2 etc). Not to sure how to implement boundary conditions at the corner. i.e. The Corner is at (i + 1/2, j + 1/2) with flow traveling in increasing i direction The B.C. for ghost pt (i+1, j) assuming zero pressure gradient, is it P_(i+1, j) = P_(i, j) or P_(i+1, j) = P_(i + 1, j+1) or P_(i+1, j) = P(1, j+1) or something completely different?:confused: Cheers, Shuo |
