Duplicate grid labels are not permitted

Recommended Posts

Hi TUFLOW FV,

I am trying to initialise a TUFLOW FV model. Once FV reads the mesh elevation levels the following error message is displayed and the model shuts down.

ERROR: Duplicate grid labels are not permitted.

A screenshot is shown below. The model previously ran through to completion although this iteration of the model includes an additional nested wave model and some changes to the BC's. It seems strange it would produce an error after reading the mesh elevations.

Cheers

Hi Rohan,

The error is most likely to you having two (or more) BCs specified on grids, but the grids have been given the same name. Double check the names of the grids you have specified and make sure they are all unique.

Hi Toby,

After checking through my model I found that the additional SWAN nest was referencing the same grid as the other wave nest. After changing the grid definition label to something different the model runs fine now!

Cheers
