Unable to open existing NetCDF file : ocean_frc.nc

#1 Unread post by chaos4u2 »

Hi, I'm trying to do my own case. It compiles well, but when I run the executable OceanG, I get this error:

NETCDF_OPEN - unable to open existing NetCDF file:
ocean_frc.nc
call from: inquire.F
I've modified all the analitical files: ana_grid, ana_initial, and all the ana's I wrote down in the header file.

This is what I put in the header file:
/* Model Physics */
#define SOLVE3D
#define UV_COR
#define UV_ADV
#define UV_VIS2
#define TS_DIF2
#define SALINITY
#define NONLIN_EOS
#define LMD_MIXING

/* Numerical Schemes Options */
#define TS_U3HADVECTION
#define TS_SVADVECTION_TL
#define DJ_GRADPS
#define MIX_S_UV
#define MIX_S_TS
#define SPLINES

/* Analytical Fields Configuration */
#define ANA_GRID
#define ANA_INITIAL

/* Surface Boundary Conditions */
#define ANA_SMFLUX
#define ANA_STFLUX
#define ANA_SSFLUX
#define ANA_SPFLUX
#define ANA_SRFLUX
#define ANA_M2OBC
#define ANA_FSOBC /* Analytical free surface */
#define QCORRECTION
#define SCORRECTION

/* Bottom Boundary Conditions */
#define UV_QDRAG /* Turn on quadratic bottom friction */
#define ANA_BTFLUX
#define ANA_BSFLUX
#define ANA_BPFLUX

/* Other Options */
#define AVERAGES
#define AVERAGES_FLUXES
#define DIAGNOSTICS_TS
#define DIAGNOSTICS_UV

Does anybody know what is the problem? Thank you in advanced.

Try undefining QCORRECTION. That term is dQ/dSST and requires two extra fields (dqdt and sst).

Thank you Kate, that solved the problem: I had to undefine QCORRECTION and SCORRECTION.

But now I get this new error:

ROMS/TOMS - Blows up ................ exit_flag: 1
MAIN: Abnormal termination: BLOWUP.

I use analitical grid (rectangular: 10000x1000x20), (Lm=100, Mm=4, N=20, NAT=2), (NTIMES=51840, DT=300, NDTFAST=45), (TNU2=5 5), (VISC2 =5), (ATK_BAK=1 1).

(ubar=vbar=0, zeta=15, u=v=0, t=20, s=38)

I think my problem is the Courant Number, but I'm not sure, here is the complete log:

You are right that something is very wrong with your Courant number, however, it blew up without even taking a timestep. Your initial basin volume is 0 - have you set a non-zero depth?

Your initial basin volume is 0 - have you set a non-zero depth?

I don't understand why the initial basin volume is 0. I've checked if I had a 0 in the depth and zeta, but I didn't.

In the ANA_GRID: I put depth = 5.0_r8
In the ANA_INITIAL: I put zeta = 5.0_r8, tl_zeta=5.0_r8, ad_zeta=5.0_r8

I turned off ANA_FSOBC and ANA_M2OBC.

May be it could be some parameter in the ocean.in file but I don't know which one is.

Also I don't understand why it doesn't change the courant number when I change DT, Lm, h or NDTFAST.

Thank you for your help.

I don't know where you set the depth to 5, but it is still getting a zero, which you can tell from this output:

I still don't find the error. I think it must be something not defined in the ocean.in file. I'll keep searching. Thank you for your help.
