Hi Josh,
RORB is expecting a hydrograph to be provided in the storm file but is failing because one isn’t being provided. If you are running standard design runs, the most likely cause of this is the print nodes in the catchment files are set to be Code 7.1, which is an interstation area meant for calibration where you provide a hydrograph to compare to. For design runs you will need to change this to a Code 7.2 for RORB to still treat it as an interstation area but not be expecting a hydrograph to be provided. This change can be done in the RORB GE.
Kind regards,
Benson
