ERROR 10021 - Error initialising external wave model grid

Description

The external wave model grid referenced by the boundary condition could not be found or has zero dimensions. This is raised when the grid label specified in the wave boundary condition does not match any grid specification loaded for the model.

Suggestions

Check that the grid label specified in the wave boundary condition matches a Grid Definition == or Grid Definition File == block in the control file. Ensure the grid specification is correctly defined.
