The TUFLOW Network Node Attributes dialog showing generic options

SMS's Network Node Attributes dialog has several new additions to the Create Connection to 2D Domain (SX) section. These new options allow controlling elevations at the connections, how many cells are connected, and the method for selection of additional cells (Grade or Sag). Each option correlates fairly directly to a TUFLOW field and some are labeled as such to make look-up easy.

The TUFLOW Network Node Attributes dialog has the following options:

  • Type – Each node can be assigned as one of the following types: "Generic", "Inlet – Circular", "Inlet – Rectangular", "Inlet – Weir", or "Inlet – From Database".
  • User specified Id – Allows specifying a name for the node.
  • Create connection to 2D domain (SX) – Connect 1D nodes to the 2D domain.
    • Force cell z to at or below node z (invert/ground level)(SXZ)
    • Lower 2D cell elevation (SXL) – Specified to connect the 1D node to the 2D domain and lower the 2D cell by the given value.
    • Don't alter cell Z
      • Method to choose additional cells
    • Method to determine number of connected 2D cells – Provides two options: "Automatic Plus" or "Specified".
      • Number of Additional
      • Number of Cells

Generic Node Options

  • Nodal area curve
    • "Overwrite existing storage"
    • "Additional to existing storage"
  • Set Channel Invert – Sets the inverts of connected channels. Default is "-99999".
  • Manhole – Allows manually defining manholes. Clicking the Manhole Attributes button will open the Manhole Attributes dialog.

Inlet Options

Weir Inlet Options

  • Shape Width – Width of the weir in meters.
  • Weir coefficient Multiplier –

From Database Inlet Options

  • Inlet database name – Contains a list of available inlets from a database.
  • Inlet Database – Opens the Inlet Database dialog.
