TUFLOW Message 1311

TUFLOW Message
ERROR 1311 - Unconnected WLL region at vertex (node)

Alternate Message
NA

Message Type
ERROR

Description
For any region (polygon) objects in the 1d_WLL layer, these should be triangles (three vertices) and should snap to ends of the water level lines.

Suggestions
Import the messages layer into you GIS package and review the WLL triangle to ensure that it snaps to the ends of the line.
In the image below, the water level lines are shown in red and the water level line triangles as white polygons. It can be seen that the error message in pink points the the location on the 1d_wll triangle that is not correctly snapped to the end of a water level line. The vertex should be moved as shown by the yellow arrow.
