60.2. Connecting a cable to any location on a net panel

Note

  • A cable to net point connection can be used to make a point connection anywhere on a net panel.
  • To showcase this feature, the completed project files from the Net extCable feature are required.
  • In many aquaculture installations, tag lines can be used to help maintain predator separation from containment nets.
  • Tag lines can also be tied off to grid plates and other moored buoys.
  • The DNetDCablePointConnection is used to connect a boundary node of a cable to a net.
  • The master of the connection must be the net.
  • The net constrains a boundary node of a cable anywhere in the net domain (not necessarily along a net element or at a node).
  • Create a new cable called tagline_1.
  • Set node 0 to (0,20,10) m and node N to (0,35,0) m.
  • Give the cable 2 elements and a length of 18 m.
  • Create a DNetDCablePointConnection between PredatorNet_1 and tagline_1.
  • Set the connection properties to $DNetMasterLocation 20 10 and $DCableFollowerNodeN 0.
  • Set tagline_1’s node N to static to fix the free end.
  • View the new tag line in the visualizer to confirm its location and orientation.
  • Run a short simulation to view the connection.
