ERROR 10028 - No polygon corresponding to ID, <polygon_id>, found in CSV file.

Description

A polygon boundary condition references a polygon ID that cannot be found in the csv polygon file. The polygon ID is matched against the ID column in the file. ID matching is not case-sensitive.

Suggestions

Check that the polygon ID specified in the boundary condition matches an ID in the ID column of the csv polygon file. Verify there are no typographical errors or extra whitespace in either the boundary condition definition or the csv file.

The use of polygon BCs has been superseded by the use of GIS 2d_sa polygon layers. If possible, consider using a GIS polygon layer instead of a csv polygon file.
