Ocean Modeling Discussion

Thanks for the great discussion, everyone. I have been attempting to quantify the turbulent dissipation for an application involving topographic wakes and I recently noticed that the suggested Kmin value for the GLS implementation of k-epsilon was resulting in extremely large background dissipation ...

Kate, as far as I can tell, the default GLS settings come from JC Warner's implementation of K-epsilon (Warner, Sherwood, Arango, 2005). Have you ever used the "gen" set of parameters? (P=2,M=1,N=-0.67)

Is there a resource out there that lists some common knobs to turn to try to prevent a model blowup? The ones that are apparent to me are: timestep/Courant number boundary conditions viscosity coefficients OBCFAC Is there something else I am missing? I am running a 3D model with an idealized domain,...

Has anyone encountered this issue in the past? I'm using a butchered version of pyroms to write my own grid and init files. Upon inspection, the netcdf files look like everything is in place, but when ROMS reads them in, it seems to skip some fields, most notably the zeta field. So instead of a geos...

Hello, I am using ROMS to do some modeling with an idealized domain. At the behest of a mentor, I have installed pyroms (which appears to be working fine) in order to overcome some of the limitations of the ana_* files. My question is, how would I use pyroms to generate a full set of netCDF files (o...

In attempting to run the channel test case, I discovered an extraneous close paren that prevents the channel test case from compiling properly. The offending paren is located in

Functionals/ana_initial, line 300, col 29.

Not sure if this is the right place for this; if not, just let me know.

My ultimate goal is to model topography in a tidally oscillating flow. For right now, I'm trying to start with something very simple and slowly build up my model. I started with the seamount example problem domain and added a West to East mean flow of 1 m/s using ana_m2obc and ana_m3obc, both enforc...

Thanks! For whatever reason I only just saw this post now. I managed to independently find the manual, but it wasn't trivial. I decided that the best thing was to just sit down and read it. It's been an incredible resource. Is there a way of having that somewhere really obvious on the wiki, or even ...

Hello, My goal here is to modify the seamount test case to have a mean flow going through the domain (i.e., to resolve the seamount wake). I'm not quite sure how to accomplish this. My research into similar issues leads me to believe that this is actually a much more complicated procedure than I ini...

Thanks, I have the netcdf fortran library installed as well (perhaps something is configured incorrectly?) bperfect@fourier:Downloads $ nf-config --all This netCDF-Fortran 4.4.3 has been built with the following features: --cc -> gcc --cflags -> -I/usr/local/include -I/usr/local/include --fc -> gfor...

I'm trying to run one of the template cases, and I'm running into what seems to be a classic library linking error: /usr/bin/gfortran -frepack-arrays -O3 -ffast-math ... /home/bperfect/roms/roms_templates/seamount/Build/libANA.a /home/bperfect/roms/roms_templates/seamount/Build/libUTIL.a /home/bperf...
