Message 10280
Available since version: 2026.2.0
Description
A column name expected by TUFLOW FV was not found in the csv file being read. The column is optional and the simulation will continue using the default value shown in the message. This warning may indicate that the column header in the file does not exactly match the name TUFLOW FV expects.
Suggestions
Check that the column header in the csv file matches the name shown in the warning. Column names are not case sensitive but must otherwise be an exact match. If the column is intentionally omitted and the default value shown is appropriate for the model then the warning can be ignored. If the default value is not appropriate then add the missing column to the csv file.
For models that include advection dispersion (temperature, salinity or tracers), sediment transport or water quality a default value of NaN typically means the model will use internal model concentrations at the boundary condition location. This can be desirable for flow extractions from the model, or in areas where the boundary condition concentration can be inferred from adjacent model conditions.
It is common for users to specify a ‘dummy’ BC Header to ensure that the BC Default value of a given header entry is used.
