Hello, dear experts
In order to achieve the duration of the full development of the scouring process in the bridge abutment, I extended the simulation time from 300 seconds to 300 seconds (from the restart time section) until I reached the time of 1200 seconds, but unfortunately, after that, the problem occurred in the time of 1280 seconds. I eat and the simulation process becomes very, very long, when I look at the exported messages window, it seems that the simulation time steps are getting smaller and smaller in 1280 seconds....
