SMS:TUFLOW Network Node Attributes

The TUFLOW Network Node Attributes dialog

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)
  • Force cell z to at or below node z (invert/ground level)(SXZ)
  • Lower 2D cell elevation (SXL)
  • Don't alter cell Z
    • Method to choose additional cells
  • Method to determine number of connected 2D cells – Provides to options: "Automatic Plus" or "Specified".
    • Number of Additional
    • Number of Cells
