My unsteady flow Plan started freezing my model after I had already created many plans on an already existing model that has been working. The model was set and I was only adding in new unsteady flow plans to run my model with. Not sure what would cause this trouble. Any help would be greatly appreciated.
I don’t know if this applies to your case, but HEC-RAS (at least up to version 6.6) allows a maximum of 99 plans (which is very inconvenient and causes a lot of difficulties). When you try to create the hundredth, it simply crashes and closes.
