Web1. For the lid driven cavity problem, we apply the Dirichlet boundary condition (or, no-slip boundary condition) to the velocity field U, that is, U = U L i d on the moving Lid and U = 0 on the rest of the boundary. Based on this, we should have U n + 1 = U n on the boundaries. Hence, if we have U n + 1 = U n − Δ t ∇ P n + 1 everywhere (as ...
