HEC-RAS Glitch?
HEC-RAS Glitch?
(OP)
Hello,
I've started a project in HEC-RAS v. 4.1 and entered in all my geometry and flow data. I'm analyzing existing and post-project information. When I go to create a plan, I'm able to create one plan and run it with no problems. When I try to create another plan, however, it gives me an error message:
"A flow needs to be specified at the top of the reach"
When I go back to my flow data, it has been erased for both existing and post project. I've tried re-starting the computer, starting a new project, etc. Several things I've tried, but I continue to have the same problem. Anyone run into this before?

RE: HEC-RAS Glitch?
The reach name for my post-project geometry did not match the reach name for my existing geometry. So when I was creating the plans, the flow data would be erased because it was trying to reference a reach that didn't have any flow data referenced to it. I went into my geometry data and made sure both my existing and post project files referenced the same reach name. Hope that makes sense.
