Hi. I’m currently using HEC RAS 5.0.5. I think it is the latest version as of now. I’m having similar errors with you. My model is a simple dam breach model where I have:

– storage area (upstream)
– SA/2D connection (dam with breach plan)
– 2D Flow Area (downstream)

I’ve tried it with and without boundary conditions (original plan is to not include any BC but just tried to put a BC downstream just to see if it affects the simulation). However, the errors are still there. Here are the errors:

Unsteady flow encountered an error.

I hope anyone can help. I've seen in another thread you can download an hdf5 in https://www.hdfgroup.org but I don't really know how to go about it. :(( Thanks in advance for any help out there.
