Ocean Modeling Discussion

Those surface stresses seem way too high to me. What forcing are you using?

ANA_SMFLUX Analytical kinematic surface momentum flux.
ANA_STFLUX Analytical kinematic surface temperature flux.

You need these as well:

# define ANA_BPFLUX /* analytical bottom passive tracers fluxes */
# define ANA_SPFLUX

Of course, that makes sense. Thank you!

I am trying to add a passive tracer to a modified seamount set up. I have changed the boundary conditions to get a westward flowing current, and now I want to add a passive tracer to part of my domain, to see what happens to the water above the sea mount (or sea hill, in this case). I set my tracer ...

Thank you Kate. I figured that might be the problem, but as I said above, I couldn't find a MyFile.dat in ROMS/External/, so I thought there might be another issue.
In any case, it works now, after I added the full path to my ROMS source, so I guess that's a qualified success

... ANA_DIAG - unable to open output file: ROMS/External/MyFile.dat ... However, if I set #undef on ANA_DIAG it runs normaly. Why ? Thanks. Gil I am getting this same error trying to run the seamount test case. I have had no issues running other applications. I don't see a MyFile.dat in the specifi...

if the domain is N-S periodic, are the results alongshore uniform? how long does this take to run? is it something i can grab and look at locally. -j There are small variations in the along shore direction, but the results are essentially uniform. The sediment bed has a very clear along shore drift...

The cross-sections are in the central part of the domain, going from the open boundary in the west to the closed, "coastal" boundary in the east. Over time, the open boundary creates eddies, and current velocities increase, especially in the north-south direction. I suspect that this is wh...

I am running a 5 year simulation of an idealized model domain, on a modified grid from the upwelling test case. I initialize my model with a uniform sediment bed thickness of 1 m throughout the grid. After around 1000 timesteps (500 model days), i start getting deposits of up to 6 meters, which shou...

I've been running a modified version of the upwelling case with (among other modifications), a uniform 1 m thick sediment bed in ROMS 3.7 When trying to change the sediment bed to have a non-uniform thickness in the entire domain, I added the following code to ana_sediment: > # if defined unised > D...

Dear Kate

Thank you for the answer. I had installed the newest version of ROMS on a new system, and tried to transfer my model from an older one. It worked fine for OMP, but trying out MPI caused problems.
I have updated all analytical files, and the model runs fine now.
Thank you again

Just to update that this issue has been resolved. The cluster turned out to not have had internet connection

It looks like you're using a revised version of varinfo.dat. Maybe check to see if the expected name for the zeta time variable is zeta_time? In my file, the relevant piece of code is in line 1005 and looks like this: 'zeta_west' ! Input 'free-surface western boundary condition' 'meter' ! [m] 'zeta_...

I made a clean install of netcdf, and it works now.

I am trying to install ROMS on openSUSE 12.3, and have installed the netcdf libraries to /usr/local/lib64, which I have also set as my NETCDF_LIBDIR in Linux-gfortran.mk. Specifically I have set it like this: NETCDF_INCDIR = /usr/local/include NETCDF_LIBDIR = /usr/local/lib64 LIBS := -L$(NETCDF_LIBD...
