After computing a model an error appears stating "H&H-SewerGEMS stopped working". Clicking on the button outlined in red above will display the Exception.log file with the following message:
"System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: Index was out of range. Must be non-negative and less than the size of the collection.
Actual value was X."
Here "X" could be -1 or 0.
The above errors may be due to RTK values in a RTK Table.
Make sure all values used are within an acceptable range (Components > Common >Runoff > RTK tables).
The RTK parameters are:
R - fraction of precipitation that enters the collection system for that component
T - the time from the precipitation pulse to the peak of that component of the hydrograph
K- the ratio of the time to peak to time to end of hydrograph for that component.
