Ocean Modeling Discussion

1. I used homebrew, not macports, and had success. So if you're more familiar with homebrew take that route. 2. Looking through my notes, I believe I got the same (or at least a similar) netcdf error as you. I tried a bunch of different things but it looks like the fix came from altering the trunk/C...

I've run on Catalina. I haven't tried on Big Sur though.

I'm very curious about ROMS performance on the new M1 chip so if you get one of those machines please keep us updated.

CoSiNE might be another one to consider.

Where are you getting your net longwave heat flux? I've had issues with unrealistic temperatures in shallow regions when applying heat fluxes. The problem is that the heat flux depends on the temperature difference between the air and the ocean, but when we take heat fluxes from some other model (us...

Thank you! I had never looked into the Quick output.

I'm trying to add new history file output fields that take a 3D field but only write the top sigma layer (e.g. SST or surface velocity). Thought I'd check if anyone else has already done this and could share some tips.

Thanks

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...

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 kno...

When you downloaded the ROMS trunk, you got the latest version. There have been some naming changes that are not reflected in the wiki yet but roms_Upwelling.in and ocean_Upwelling.in are effectively the same, just with a different filename. That particular change is only a few weeks old: https://ww...

Can you post the rest of the output? The information about what's causing the problem will be higher up in the file.

I had this issue in the past but I don't remember what I'm doing differently now so that I don't have the issue anymore. My work around: sort the time variable (so that time is strictly increasing) and then sort your other variables' time dimensions to match.

Thanks Kate

Page 56 of the HYCOM user's guide https://hycom.org/attachments/063_hycom_users_guide.pdf 20.3 Generating "Equal-Ocean" Tile Partitions, looks like the most promising lead so far.

I'm interested in defining an application-specific grid. Motivation: if we have a grid where the standard domain decomposition results in one or more tiles (MPI processes) that are composed entirely of masked out land cells, then this seems like an inefficient allocation of our computing resources. ...

Hi I'm looking for some hints pointing me towards papers that have looked at the role of baroclinic processes in water mass exchange/flushing. I'm having trouble finding what I'm looking for and I wonder if maybe I'm using the wrong jargon. I've been shocked by the magnitude of the differences betwe...

Hi I didn't see your log file attached but if it's blowing up at the beginning of the run you could try adding the option and recompiling.

Hi, attempting to build a NetCDF forcing file with the included frc_rivers.cdl (found in Data/ROMS/CDL/) may return errors due to a few missing commas. Pasted below is 1. the difference between the fixed and the original, 2. the original version, and 3. the fixed version. $ diff frc_rivers_original....

Upon moving to a new machine I am experiencing this exact problem. I wish the other users who experienced this problem had reported back with their solution...

Thank you for your reply Charles. A couple of days ago I did switch out all the instances of function " any " to agree with the new r2014b graphics handles but you are right about there still being other issues. Unfortunately, I am not a Windows machine so I think for now I will just locate an older...

John, I too would greatly benefit for your colleague's seagrid advancements. I am attempting to get seagrid working with r2014b but the new graphics system is causing many compatibility issues.

Thank you

Have you updated your mex files yet? I believe that is my issue, though maybe you have already updated them. From the SEAGRID README.txt in the mex file subdirectory Building SEAGRID requires building 3 mex files: mexsepeli.F mexrect.F mexinside.c These mex files are machine dependent, and can also ...

I am having the same problem, kindly let me know if you find a solution.

Thank you
