Yes. I created the new contacts file (ngc file) with the script provided by ROMS .

Nesting problem:Subscript #1 of the array IDG has value -999

Hi ROMS team, When I run ROMS nesting case, at first time it ran successfully. When I change the grid region, it fails. the erro is Subscript #1 of the array IDG has value -999 which is less than the lower bound of 1 The value IDG is in the nesting ngc file, but I searched it, there is no number low...

Re: BLOWING UP during nesting

I only added the initial condition, the tidal forcing and the contact files for the refined grid. Can you clarify this sentence? You don't have a tidal forcing file for the refined grid so are you saying that you haven't run the coarse grid standalone with its initial conditions file or its tidal f...

Re: BLOWING UP during nesting

1. Is that your full output file? Where are the lateral boundary conditions and C-preprocessing options etc.? 2. What is your grid refinement factor? This should dictate your DT. E.g. if it is 3x refined, it's typical to use a 1/3 smaller DT for the refined grid (so 3 s instead of 15 s). I don't kn...

BLOWING UP during nesting

Hi all, I run a coarse resolution case successfully, I would like to choose a small area of the case area to study the phenomenon of multi-layer nesting in the area. But now only 2 layers nesting failed. I do not know the reason. I created the refine grid file with the Matlab code coarse2fine. I ext...
