Ocean Modeling Discussion

Kate,
thank you for the reply. i will try that.

Hi,
I am having problems with setting analytical point source. Do i understand it correctly that to set a direction of the inflow water i have to set Dsrc (0 toward east and 1 toward north. or when 0.5 then it would give NE wind?) and Qbar (when positive then along u or v direction and negative to ...

Hi Austin,
Thank you for the reply. I made that mistake too at the beginning but i already figured out my self before and now i have under mask h = 2m that is my hmin. Did you use any other way to smooth topography?

i modified ana_psource.h to have right locations for i and j. also moved it around ...

Hi,
I am trying to run simulation with rivers for Gulf of Riga using realistic topography.
When i add ana_psource i get several problems that i do not seam to be able to figure out:
1) salinity values get unrealistically big (initial salinity 5psu and input 0psu, i get salt values 30psu and up ...

thank you for the reply.
looks like that specific error was caused by the attempt to add tides only from one boundary (or over complicating with attempt to modify ana_m2obc.h file, got working and good result with using only zeta on all open boundaries at the end of ana_fsobc.h file).

Hi,
I try to add tides from open boundaries for analytical idealized domain river inflow case.

#define EAST_FSCHAPMAN
#define EAST_M2FLATHER
#define EAST_M3RADIATION
#define EAST_TRADIATION
#define ANA_FSOBC
#define ANA_M2OBC

I changed ana_fsobc.h and ana_m2obc.h files and directed in wiki for ...

error is on the first step of model run. debud dont help, thats how i got seg error, parallel error was even more useless :).
i think it is most likely to be memory problem cos same run that runs on 8clusters refuses to run on any less number of clusters so i suppose there is nothing much i can do ...

if it is problem in parallel i cant imagine what kind of problem. as i said exactly same run with 20layers works fine on parallel.

thank you for the reply.
i have been trying to figure out if it is memory issue.
my domain size is not too big 128x256x30 and to run on 8 cluster. how much memory should one have to perform such a run? i set as many of parameters in ulimit as high as i can. is there anything else i should be able ...

i am having a trouble with idealized analytical case that i try to run.
domain is rectangular basin, depth changing from 5-15m to offshore direction and fresh water inflow from point source in one location.

when i try to add vertical (to use 30 layers.. worked nicely with 20layers both on ...

Hi,
i am having problem with running riverplume2 test case.
i get negative ubar values inside the river part i.e. water is flowing back to the direction of point source couple of steps away (zeta and vbar changes dont even seam to be big enough for it). i use five point wide inflow, open boundary ...

hi,
I hope that somebody might be able to help me with my problem.
i am using ROMS (agrif version) and i try to compile my files. I use linux and g95. it keeps giving me error that looks like it cant find netcdf library or something.
i have set path for libnetcdf.a and netcdf.inc files in jobcomp ...

I am trying to compile initial package in fortran but then I get strange thing.
Error occurs in def_out.F:

In field def_out.F:167

lsdim=Vname(6,idVbar)

Error: Can’t convert character to integer(4)


and indeed Vname(*,*) is defined as character and lsdim is defined as integer. I don’t ...

So there is two different versions of roms? I kind of understood that one had developed out from other?
But all questions and everything in forum seams to be about roms-2.2 and i can find hardly any info about roms_agrif version besides? i do have matlab scripts just that roms-2.2 do not seams to ...

How i know what should be in my ocean_*.nc files? This packages seams to provide single field netcdf files. How do i know what exactly must be in them? And do they have to be already interpolated to the grid or can roms do it?

How do you get from your data files (usually ascii format?) netcdf files?
as much as i can understand from this program i need to provide some netcdf files in ocean.in file.

there are no f771 files in my computer not .exe or any other

Hi,

I am trying to switch from an old version of ROMS (with “preprocessing tools” and “Run” and so on) to the new ROMS 2.2. that have a totally new structure and I am having some difficulties with that. My main problem is that I don’t understand what is replacing preprocessing part. How I am ...

hi, i have problem when i try to use forcing package to making NetCDF file for windspeed and momentum stress (i.e with forcing fields with vector data, other forcing fields with scalar data work).
error is:

DEF_VAR - unable to define variable: Uwind in NetCDF file: windspeed.nc
Invalide dimension ...

have you found this page? i was tring to locate that wiki stuff too but havent found it so if anybody could add here link it would be realy helpful
