Solids Builder - SWMM Nodes - Outfall

The outlets are end nodes of the drainage/sewer system used to define the final downstream boundaries under Dynamic Wave flow routing.

When you want to define a device as an output, you must add the tool Outfall to the Constructor:

When adding the tool Outfall, fill in your properties, in the tool's properties frame:

In the Constructor, the following properties must be filled in:

• Identification
  • Name - name of the activity
    The point name must follow the naming rules
  • Description - when the name of the activity is not enough to give context to the activity, use the description field
• Outfall Type
  • Outfall Type
    • Free - output stage determined by minimum critical flow depth and normal flow depth in the connecting conduit
    • Normal - output stage based on normal flow depth in connecting conduit
    • Fixed - output stage set to a fixed value
      Enter the fixed stage value in the Constructor
    • Tide - Tidal Curve
      In this case, enter the Tidal Curve that describes the height of the tide versus time of day in the Constructor
    • Time Series - Time Series
      In this case, enter the name of the User-defined time series of stage versus time in the Constructor
• SWMM
  • Retention Device - Indicates if the device has a retention gate
  • Bottom Elevation - Elevation of the bottom of the node (radier elevation)
    Must be associated with the property of the constructor that manages the device's Sump Elevation

A Manhole device can play the role of Junction also, So you have to anticipate these situations. In SOLIDOS it is simple to do this without having to create two different Constructors. For example, consider the simple circular manhole shown in the catalogue:

This manhole will be a typical SWMM node unless it is the endpoint of the network, perhaps because it interconnects into an existing network. To differentiate, you can check if there is a device connected to its output, like this:

Using the Get Property tool, you can get the device name connected to the manhole outlet, like this:

The block Try Catch catches the error that occurs when the activity tries to get the name, because if there is no pipe connected, there is no way to get its name. Thus, one can conclude that the manhole is a Outfall and not a Junction. To define within the Try Catch block, add the exception:

With the following properties:

In the example, SumpElevation is the property that represents the bottom elevation of the manhole:
