Hi, sorry for my english, I hope it’s understandable.
I had the same problem with my simulation. To solve the problem it’s very important to set the
“Ending Date” in the “Simulation Time Windows”. Remember to fill the temperaure table in the
“Quasi Unsteady Flow Editor” and save all files (Geometry, Quasi Unsteady, Sediment) before every run.
Altough you can look datas in the dialogue boxes, HEC RAS don’t use the datas for computation before
you click on “save” button.
