Hi woida

I don't have an answer to your problem, but I am really interested how do you get a 15 percent steep torrent stable in unsteady calculations? Do you have a very regular geometry (a channel) or is it a natural torrent? I am struggling with 1 percent steep river, I get it stable but without 5 percent steep block ramps. I would appreciate any hint.
Did you try ramping down the model to create a restart file?
