Node Results Data Fields (InfoWorks)

Node results are displayed in the Node Results Window (that can be found as a tab in the Results Grid Window of the Network page) and on the Node Object Properties Window while viewing a replay of a simulation.

Time varying results are shown with the field name in an alternate colour on the grid. Non time varying results have the field name in the normal black type.

Level in 2D Zone

Applicable to 2D nodes only.

Level in the 2D mesh at the node at the current timestep.

For Connect 2D nodes, the Level in the 2D Zone depends on the connection type:

  • Closed, Lost or Break - the level is undefined (as there is no associated 2D element).
  • 2D - the level is either undefined if depth is zero or the level in the 2D Mesh at the node.
  • 2D Line - the level is either the maximum level amongst the 2D elements associated with the node through the 2D line connect object, or undefined, if depth is zero in all the associated 2D elements.
