WARNING 10128 - Nodestring overlap found between Nodestring ID=<nodestring_id_1> and Nodestring ID=<nodestring_id_2>.

Description

Two nodestrings share one or more common mesh faces. This can occur when nodestrings are digitised with overlapping segments or when two boundary condition lines cover the same mesh edges.

Suggestions

Review the two named nodestrings in the mesh or GIS editor and check for shared faces. If the overlap is unintentional adjust one or both nodestrings so they do not share any mesh faces. If both overlapping nodestrings are assigned as boundary conditions ERROR 10116 will also be raised.
