I was running a 1D steady flow model with 2 geometry files and 1 steady flow data file as below:
Plan A - Geometry A + steady flow data
Plan B - Geometry B +steady flow data
I first run & save plan A, then create another plan B. But after I've run plan B with geometry B, if I go back to look at Plan A, the geometry data automatically became geometry B. If I run plan A again with Geo A, opening plan B would end up with Geo A again.
I'm still quite new to HEC-RAS, I was wondering if anyone could tell me what I've done wrong?
