WARNING 10389 - External GIS nodestring has failed to build successfully.

Description

A GIS nodestring could not be built during mesh initialisation. This warning is raised for each individual failing nodestring. If any failures occur ERROR 10149 is also raised as a summary.

Suggestions

Check the GIS geometry for the failing nodestring. A common cause is a path that cannot be resolved to a sequence of cell faces. Adding additional vertices along the nodestring can help the path algorithm find a valid route through the mesh.

If the nodestring is intended for hydraulic structure assignment or flux reporting ensure the BD flag is not specified in the 2d_ns GIS layer. The BD flag is only for nodestrings that need to be projected onto the boundary of the mesh.
