Ocean Modeling Discussion

Hello, I looking for some information about how to set up ROMS_AGRIF in 2D including AGRIF technique.

Thanks!

Thanks!

I thought if I activate SSH_TIDES the model will force all the domain and not just the boundary. I'll try it!

Hi! I'm doing a model with which I want to see how the tide within my domain. For that I will force only open boundaries and see the tide as it spreads into my domian. I have the tidal forcing files created from frc_tides.cdl for each boundary of my domain (just amplitude and phase of 14 harmonics ...

I have the tidal forcing files created from frc_tides.cdl for each boundary of my domain (just amplitude and phase of 14 harmonics extracted from FES2004). And now I want to force only the boundaries. My question is: how must I indicate to ROMS that it use frc_tide_south.nc to force the south open ...

I want to do it with realistics information. I work with FES2004 to get data of a global model to force my regional model, so I should have a boundary file with a temporal series of the surface elevation for each edge.

Hi! I'm interested at the 3° option, but I don't see how putting a temporal serie of "zeta" in the boundary netcdf file. I choosed this option because I want to see how evolve the tide on my coast.

I solved my issue, it was a mix of grid setting and the forcing.

Thanks!!

I made the build.bahs with USE_DEBUG and I got this forrtl: severe (174): SIGSEGV, segmentation fault occurred Image PC Routine Line Source oceanG 00000000004BDC68 set_vbc_mod_mp_se 180 set_vbc.f90 oceanG 00000000004B9C8C set_vbc_mod_mp_se 63 set_vbc.f90 oceanG 0000000000497F48 main2d_ 122 main2d ...

Hi, I have the same issue, but I'm with oceanS and setting a grid netcdf file. When I run it: log file: NL ROMS/TOMS: started time-stepping: (Grid: 01 TimeSteps: 00000001 - 00002016) STEP Day HH:MM:SS KINETIC_ENRG POTEN_ENRG TOTAL_ENRG NET_VOLUME C => (i,j) Cu Cv C Max Max Speed 0 0 00:00:00 0 ...

Hello, my problem was that my model is barotropic, so the flux wasn't affected by a low viscosity. I incremeted the value to 5000 and this worked. I think that more efficient, in my case, is to use nudgings options.

Thanks!

Hello, I'm trying to set a sponge layer in the western and eastern edge. So I modified ana_sponge: width=20.0_r8 !20 == 200 km MIXING(ng) % visc2_r(IstrT:IendT,JstrT:JendT)=0.0_r8 MIXING(ng) % visc2_p(IstrT:IendT,JstrT:JendT)=0.0_r8 ! ! Eastern edge. ! DO i=MAX(IstrT,Lm(ng)+1-INT(width)),IendT DO j ...

Thanks! I thought that both ROMS were the same, I use roms.org. So I must modify only ana_sponge.h, therefore just with: width=20.0_r8 MIXING(ng)%visc2_r(IstrT:IstrT+INT(width),JstrT:JendT)=5.0_r8 MIXING(ng)%visc2_p(IstrT:IstrT+INT(width),JstrT:JendT)=5.0_r8 MIXING(ng)%visc2_r(IendT-INT(width):IendT ...

I solved it, I was thinking all in kilometers. I read fully ana_grid.h and understood how is created the grids points.

Hi! I'm testing the OBC. But when I set a sponge layer I think that ROMS don't read it. In my *.h I have: #undef SOLVE3D #define UV_COR #define UV_ADV #define UV_VIS2 #define UV_QDRAG #define NONLINEAR #define ANA_GRID #define ANA_INITIAL #define ANA_SMFLUX #define ANA_DIAG #define AVERAGES #define ...

Thanks a lot, I used this to start my idea. I proposed this in ana_initial #elif defined CANAL x0=xl(ng)/2.0_r8 y0=el(ng)/2.0_r8 DO j=JstrT,JendT DO i=IstrT,IendT x=(xr(i,j)-x0) y=(yr(i,j)-y0) alfa=(x*x+y*y)/200.0_r8 zeta(i,j,1)=EXP(-alfa) END DO END DO DO j=JstrT,JendT DO i=IstrP,IendT ubar(i,j,1 ...

Hello,

I want to do a simple test to compare the open boundary conditions. To do it, I'm going to set a initial surface elevation and let this evolve. So, how I can set a gaussian, for example, as a initial condition of surface? I didn't find something like this in the manual.

Thanks!

Hi! I can do it. All links was directed to different directories. I started again and it worked.

Thanks!

Hello, i'm trying to compile ROMS through build.bash. But during this compilation, it shows: [...] /home/matias.dinapoli/ROMS/Base/Build/libMODS.a(mod_netcdf.o): In function `mod_netcdf_mp_netcdf_open_': mod_netcdf.f90:(.text+0x1d0ba): undefined reference to `netcdf_mp_nf90_open_' mod_netcdf.f90 ...
