ERROR 10119 - Duplicate Polygon/Point id: <point_label> found in <file_name> files.

Description

Two or more GIS objects within the same GIS layer share the same ID. Duplicate IDs within a layer are not permitted as they cause ambiguous boundary condition assignment.

Suggestions

Open the reported GIS layer and ensure each polygon or point has a unique ID. Rename any duplicates and rerun the simulation.
