ERROR 10249 - Error processing output curtain object. Inadmissable cell index.

Description

Raised when constructing a curtain output object and one or more of the interpolated cell indices along the curtain polyline falls outside the valid range of mesh cell IDs. This indicates an internal mapping error between the curtain polyline and the mesh.

Suggestions

Check that the curtain polyline file specified via Output Curtain File == is valid and lies fully within the model domain. If the polyline is correct, contact support@tuflow.com and please provide the TUFLOW FV log file and the curtain polyline file, this will help diagnose the issue.
