I am facing an error while I am running the SewerGEMS Model, what that message and how can fix it?
The model shared for your review.
Regards ......... Mohamad
Thank you for support - everything now is configured well.
Hello Mohamad,
I checked your model and there are many inlets which serve as the start node for more than one gutter. This number is quite high. Following is the user notification I am getting;
"This catch basin is the start (upstream) node for more than one gutter. Only one gutter is allowed to come out of a catch basin node."
Have you resolved this user notification? That is reversed the gutter alignments at the problem locations?
If yes. please share the updated model with me.
Here is a wiki article which would be useful for bulk node reversal;
Reversing orientation of Pipes and Conduits in Bulk
Let me know if this helps.

Hello Yashodhan
I adjust "Use Local Rainfall? but the problem still there when the model validates the gutter, would you please revisit the model and advise.
Thank you,
Mohamad
Hello Mohammad,
Please check your catchment properties. See if you have set the "Use Local Rainfall?" to "True" and not selected any storm event for it. This could also happen if there are multiple downstream gutters when using the Explicit SWMM Solver. The below wiki contains these options in detail;
Error computing model: "Calculation cancelled by user" OR "Specified cast is not valid" OR "An item with the same key has already been added"
Hope this helps.
