Ocean Modeling Discussion

Hi Kate,

I followed your suggestion in the previous post and my problem was solved when I changed:

from: character (len=1024) :: string

to: character (len=4096) :: string

And after I ran the application again: ./build.bash -f and mpirun -np 54 ./oceanM ocean_river.in.

Thank you.

Hi everyone,

I am having problems running my application when I increase the input file number.
I knwo there is a limit (https://www.myroms.org/forum/viewtopic.php?f=14&t=4323&p=16638&hilit=forcing+input+file+limit#p16638), and I have fixed that question changing the Cval dimension in the files ...

Thank you Kate, my input files are working now.

Yes, I tried to change from 200 to 400, but unfortunately didn't work.

/src/ROMS/Utility/read_phypar.F
line 95

from
character (len=256), dimension(200) :: Cval

to
character (len=256), dimension(400) :: Cval

Maybe is necessary changing something else, I don't know.

Thank you Kate,

I have 200 files from Y2008M10 until Y2010M5, and if I include one more the error appears.
Should I reduce the number of input files or there is some way to change read_phypar.F?
Thank you again.

Hi all,

I wonder if there is a limit of input files in the roms.in.
I have created my input files in the same way and included in the roms.in, as follow:

BRYNAME == ./input/roms_bry_HYCOM_Y2008M10.nc |
./input/roms_bry_HYCOM_Y2008M11.nc |
./input/roms_bry_HYCOM_Y2008M12.nc |

Hi,

Thank you so much, your suggestion about the rain fall solved my problem.
Actually, my rain fall input data were wrong, they were in mm/day, and not in kg m-2 s-1.
My experiment is going very well.
Thank you again.

Hi all,

In order to facilitate the understanding of my input data, I have selected a point in the deep ocean (-37.792; -15.138) to show the time series of all my input data requested by ROMS in the simulating using BULK_FLUXES option, as I showed in my first post. I attached two plots of them ...

Hi Kate,
Sorry, I did not say my units in the post.
I have checked all my variables and units, and if they are according to the varinfo.dat.
Follow below:

- Uwind_CFSR.nc: m/s
- Vwind_CFSR.nc: m/s
- Pair_CFSR.nc: millibar
- swrad_nam_CFSR.nc: w/m2
- lwrad_down_CFSR.nc: w/m2
- Tair_nam_CFSR.nc ...

Dear roms users,

I'm new user of ROMS model and I'm having some problems about the use of BULK_FLUXES. I downloaded all the necessary information from CFSR/NCEP, 6h-6h (http://nomads.ncdc.noaa.gov/thredds/dodsC/modeldata), but the wind-stress and surface net heat flux of model results are not real ...

Hi,

I am using the Roms Agrif version in an interannual experiment (October/2015).
Using data from HYCOM to generate CLM file, I modified the create_clim to avoid large netcdf file.
I modified the code of create_climfile.m file:
from:
ncid=netcdf.create(clmname,'64BIT_OFFSET');
to:

Someone can help me with this problem?

Hi,

I'm with a serious problem with Matlab 7.8.0 (R2009a) and the NetCDF.

So, I'm begin in ROMS Model, and I don't know how set up my Set Path correctly at Matlab.
I downloaded the Roms Netcdf Toolbox, which contain the following files (I think they are the main):

./main_data
./matlab
./matlib ...

Hi People,

I'm following strictly the steps of the MATLAB TOOLBOX TO ROMS.
I created my grid without problem:

grid: coast-grid.nc
coast: east_brazilian_coast.mat
indices: ijcoast.mat
lon: 4648x1
lat: 4648x1
Icst: 4648x1
Jcst: 4648x1

Apparently the netcdf package worked very well.
To do this grid ...

People, I have installed a new version of Matlab. I already download the matlab-toolbox-roms.
So, the problem appear when nothing is working anymore.
I can't find a mexnc and snctools compatible with this new version of matlab to create a grid file with seagrid.

I'm severely thinking to change to ...

Hi everybody.
I have the same problem of DREWA, in the top of the session.
drewa, do you solved the problem?!
Someone can help us?!

Thanks!

Hi everybody,

When I execute the file seagrid2roms.m, an error appeared in the line 200.
disp(' ## Defining Dimensions...')

nc('xi_psi') = L;


The error is:

??? Error using ==> finite

I'm creating a grid file with matlab and seagrid.
I'm following what is write in the file MAIN_grid.m.

The error is:

>> mex rnt_hindicesTRI_mex.f

mex: compile of 'rnt_hindicesTRI_mex.f' failed.

??? Error using ==> mex at 206

Kate, I had installed correctly the libgfortran.
So, I think that the file mex can't be changed, because the following error appeared:

>> mex rnt_hindicesTRI_mex.f
g95: Unrecognized option '-c'

mex: compile of 'rnt_hindicesTRI_mex.f' failed.

??? Error using ==> mex at 206

Thanks Kate, but other problem appeared:

It worked! Thanks a lot.

Other problem persist.

Hi dears,

I followed what is write in the file MAIN_grid.m.
I created my grid file, using all the packages mentioned, including seagrid.

My problem appear when a typed:

Hi people,

I ran correctly the test case UPWELLING, but now I want to do the same thing with the river_plume1 test case.
I followed the same steps, I copied the files varinfo.dat and ocean_riverplume1.in from src/ROMS/External to my folder /projects/river_test1.
I copied the file riverplume.h from ...

Thanks Jungwoo Lee,

I asked this question because I want to put my own input files of grid, forcings, so on, following this test.
So, the test doesn't call any input file? Then, how the model make all the calculus? With which input data?
The first step to put my case is upload a "myfile.h", so ...

Hi people,
My question is so simple.
I run the test case Downwelling/Upwelling, but I can't find the files ocean_grd.nc and ocean_ini.nc.
Where is the input files which the ROMS uses to run this test case?
I would like find it because I want to replace with my input files.

Thanks anyone who can ...
