TUFLOW FV

Available since version: 2026.2.0

ERROR 10323 - No polygon corresponding to ID, <polygon_id>, found in file.

Description

TUFLOW FV could not find a polygon with the specified ID in the polygon csv file. The zone ID named in the message does not match any entry in the file.

Suggestions

Check that the zone ID in the structure definition matches an ID in the polygon csv file. IDs are case-insensitive but must otherwise match exactly. Verify the correct file is referenced using Polygon File ==.

TThe polygon csv method is deprecated. It is recommended to use the Read GIS Zone == command to assign polygons via GIS integration.
