Adding
#define ONE_WAY
to your 'application'.h file where you defined NESTING will limit the nesting to one-way coupling.
The will not correct issues associated with poorly defined metrics or inconsistent bathymetry. I suggest it as a means of bypassing this unresolved issue https://www.myroms ...

Re: ROMS Nest Boundary problem
Your errors look similar to ones I recently encountered while using two-way coupled in deep water. There are a several things that should be checked, including the consistency of the metrics between grids and consistency of the bathymetry. Check the suggestions made to me by John Wilkin in https ...

Error in Flux Integrals in Correct_Tracer - two-way nesting
I've been struggling with a deep water :arrow: two-way nesting issue and after a few false starts I have followed the problem to and into the correct_tracer_tile routine in nesting.F.
The fine grid flux integrals in correct_tracer_tile do not properly account for the coarse grid time interval ...

Re: Difficulty with two-way deep water nested grids - update
I continue to have difficulties with two-way coupled nested grids, but with John Wilkin's guidance have been able to clarify a few things. The inputs are derived from an NCOM run, Atmospheric inputs derived from WRF and Gebco bathymetry.
1. I've confirmed smoothness of bathymetry at and near the ...

Re: Difficulty with two-way deep water nested grids
John,
Thanks for the suggestions. I'll follow up on them. I believe the code used to interpolate from the the original single domain case to the nested case was based on d_roms2roms.m.
I do have a question on the the output file 'fort.300'. What is acceptable error magnitude for mass conservation ...

Re: Difficulty with two-way deep water nested grids
Thanks for the reply.
I thought about the initial transient. I ran the synchronized case as a way of discriminating between the IC issue and a possible time stepping issue associated with 2-way coupling in deep water. If it was an initial conditions problem, I believe the waves should have ...

Difficulty with two-way deep water nested grids
We are trying to run ROMS in a well resolved nested deep water (h ~ 5000m) configuration and have encountered a difficulty. We are using three nested grids at a grid ratio of 1:3. On the coarsest grid, dx ~ dy ~ 800m while at the finest dx ~ dy ~ 89m. The initial condition is derived from NCOM and ...
