On validation I get the "Only one gutter is allowed to come out of a catch basin" error. I checked all the structure rim elevations as suggested but I still get the error. The elevation of the rims is coming from the finished surface that I am using to insert the structures.
Hello Asinati,
I have updated this link to include another possible issue: The 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.
Check the start and stop nodes for the gutters attached to the catch basin to see if two gutters are using the same catch basin as the start node. If so, you will need to use the Node Reversal property in the gutter properties to reverse one of these.
Regards,
Scott
I checked the catch basins with the error message and none of them have more than one gutter coming into them.
Try the following:
1. Open the gutter FlexTable (Subsurface Utility menu > View > FlexTables) 2. Select the Hydraulic Analysis tab from the FlexTables dialog. 3. Open the Gutter Table. 4. Right-click on the Start Node column heading and select Sort Descending. 5. Notice that there are two gutters that have "Inlet78" as the start node, which are "Link9" and "Gutter -5".
To delete one of these gutters, right-click on its row heading and select Zoom To.Then hold right-click in the drawing pane and select delete element.
