Thanks, amazing presentation, amazing work (Dog also amazed at subgrid bathymetry, 19:11)

Hello, according to the reference manual, in the SWE, the cell velocity is approximated from the face normal velocities. The cell center velocity terms that stem from the weighted least squares method are provided. However, it is not clear how to calculate wk (weight of face k) found in the terms. Inspecting Perot's (2000) paper hasn't helped.

I think at 9:05, you mean that all cells in the 2D computational grid mesh must by "convex" polygons. I don't think that they can be concave.

Good one

Increases velocity near the banks and decreases velocity in the middle!? I thought it's opposite
