payam.h is on a distinguished road
Hi
I have some problems in flow 3D.
first ,I am simulating a 2.5D ogee spillway . The number of cells of mesh is approximately 1400000. Run time is 3 days for 30 second. That's too much time for this model. I don't have sediment and just consider hydraulic of flow.
second, I use this boundary condition for model :

I think may be boundary condition in Xmax is wrong.
I choose outflow for Xmax.

Thanks in advance for your help
