I saw your post and I am having similar issue. I entered the user curve for the gates and added a dummy gate at the inlet elev. I keep getting the following error.
Error running the unsteady post processor: Ryan3 unsteady
DSS File used: C:\Projects\Projects\Ryan_Dam\Ryan3unsteady.dss
Error reading data from path: /TROUT BROOK STREAM/34.5 INL STRUCT GATE #1/GATE OPENING//1HOUR/PLAN 03/
There was no data for this time window, but a record was read.
Any ideas??
Thanks
