Ocean Modeling Discussion

hello, I want report an issue that I encounter recently. I am running a realistic ROMS-only test that receives freshwater input from a small river (see attached figure). This test incorporates tides and atmospheric forcing (winds, heat flux etc). The grid spatial resolution is around 8-20m. Wet-dry ...

Hello, I am not sure whether anyone has seen or reported a similar problem. I am running a ROMS-SWAN coupled realistic model. The model grid has three open boundaries (south, west and north), and the eastern boundary is closed. SWAN model receives realistic incoming wave forcing from a boundary cond...

The issue is now resolved after adding these lines in the SWAN INPUT files: INPGRID CURRENT CURVILINEAR 0 0 481 908 EXC 9.999000e+003 & NONSTATIONARY 20150718.000000 24 HR 20150719.000000 INPGRID WLEVEL CURVILINEAR 0 0 481 908 EXC 9.999000e+003 & NONSTATIONARY 20150718.000000 24 HR 20150719....

Here are the files:

(1) two PRINT* files (SWAN uses 30 processors so there are 30 copies);

(2) SWAN INPUT file (swan_LPL.in);

(3) ROMS INPUT file (ocean_LPL.in);

(4) header file (lpl_couple.h).

hi John, yes, the coupled model has wet/dye on. I did not turn on the 'ZETA_CONST'. The pcolor plot at 07/18/06 is attached. So it is clear that the 2.25m is the 'zeta' on land. Below are the lines from ./SWAN/Src/waves_coupler.F (L1250 - 1270). If I understand correctly, the calculation of the Min/...

Hello, I am reporting a potential issue with SWAN model that is coupled with ROMS. In my case, ROMS has barotropic tides and the sea surface level varies with an amplitude of ~1.0m. Within each coupling interval (12 mins), the log file clearly shows that ROMS and SWAN exchange information (see an ex...

Thanks, John!

I got the reason for my problem. The high resolution grid plus 'diagnostics' overburden the the desktop, thus it terminates in the very beginning. It runs well on cluster now.

Hi,all! I run across this errors with a ROMS+SWAN coupled case. The case runs well if 'DIAGNOSTICS_UV' is unactivated. But once this cpp gets activated, the running terminates at the very beginning with the details shown as the following: Coupled Input File name = Projects/Stormsrun/TS/Nest_TS/Facto...

Hi, everyone! :) I want to ask a question about SWAN model if applied in polar (arctic or antarctic) area. The angles calculated from the coordinates in the grid file may not satisfy the prerequisite, as it says in SWAN manual "SWAN will check whether all angles in the grid are >0 and <180 degr...

Hi! I want to ask if anyone get the same error message as i get about the cpp 'WEC_MELLOR'. After i update COAWST to version3.1, i get error during the compiling if i activate the cpp 'WEC_MELLOR'. And i try to go back and check the file 'wrt_his.F'. I find that the line 3314 was written as 'status=...

Thanks very much! I just figure out my problem. The problem comes from the code that i used to create the NetCDF file for wind stress. The original matlab code was written as: v1 = netcdf.defVar(nc,'sms_time','double',[time_steps one]); % Here 'time_steps' is a self-defined parameter. Because the ne...

Hi! Can someone tell me how to set or create the 'time' string within the netcdf file? Now i try to use COAWSTv3.1, and i can find there is a new file 'check_multifile.F' (COAWST/ROMS/Utility) that do the file checking. But i dont know how to create such netcdf files (One example is that i want to c...
