Ocean Modeling Discussion

Posting on behalf of Dr. Anne-Claire Bennis Dear all, The Continental and Coastal Morphodynamic Laboratory in Caen (https://www.unicaen.fr/m2c/) invites application for a 18-months research engineer position in numerical modeling to simulate hydro-sedimentary processes in nearshore zone. We are seek...

Hi Aryan, Can you please clarify if you are using ROMS or COAWST? If former, I am not sure if ANA_WWAVE is completely tested to be able to provide one-way wave-current interaction. If you are using COAWST then you can provide an input forcing file with your choice of wave input. In this case you wil...

Dear ROMS Folks, Please consider submitting an abstract to the "The Inner Shelf - Opening the Black Box Connecting the Coastal Ocean and the Surf Zone" session at the 2018 Ocean Sciences Meeting to be held from 11-16 February, 2018 at the Oregon Convention Center, Portland, Oregon. Website...

Hi Kate Thanks for getting back to me. I reverted ran_state.F to svn version 842, and now the code compiles, and I can run upwelling example. However, I do get a warning saying: ran1.f90(47): warning #6046: The INTEGER(KIND=2) value is out-of-range. [2147483579] IF (rans.lt.0) rans=rans+2147483579_i...

Dear All I am trying to compile ROMS (checked out today using svn) in a new Linux server with Intel Fortran Compiler and OPEN MPI and get this compilation error: ran_state.f90(112): error #6284: There is no matching specific function for this generic function reference. [REALLOCATE] ranseeds => real...

Kate

I am looking into dimension mismatch cause, and will let you know if I can find a fix to the problem.

Thanks

Hello Kate As suggested, I added a print command in mod_netcdf.F. After recompiling and executing the code, I get following error: NLM: GET_STATE - Read state initial conditions, t = 0 00:00:00 (File: mbcamelot_init1_06112010.nc, Rec=0001, Index=1) - free-surface (Min = 0.00000000E+00 Max = 0.000000...

Hi Kate Thanks for the reply. I did update to latest ROMS(v470) and tried to do a simulation. The error I get in that case is: Maximum barotropic Courant Number = 1.29657294E+00 Maximum Coriolis Courant Number = 7.29000000E-04 NLM: GET_STATE - Read state initial conditions, t = 0 00:00:00 (File: mbc...

Hello Everybody I am using a coupled ROMS_SWAN application for surf zone. ROMS Version 240 I know this is an older version and latest svn update is around 470. But the reason to use this version is to compare my model results to a set of older model results from ROMS (Version 240) Domain Description...

This is line 160 of ocean_coupler.f90
Also if required, Line 105 of ocean-control.f90 is

Hello Everybody I am trying to setup ROMS for a new Linux-cluster and having some issues. Before I jump to the issue I will provide you with some details of the Linux cluster: uname -a command gives the following output: Linux acm-chem.psc.sc.edu 2.6.18-128.1.14.el5 #1 SMP Wed Jun 17 06:38:05 EDT 20...

I am using it for study of nearshore circulation in South Carolina...

Hernan Sorry for the delay in replying. I was having issues in connecting to the cluster. To answer your questions: (a) I was using revision 305 as I checked my version after posting the message The GET_CYCLE message comes twice as I did a mistake while copying and pasting it, when posting the last ...

Hello Everybody I am using ROMS with SWAN for a surf zone application and I had been using ROMS Revision (240). Today I updated my ROMS code to Revision 305 and tried to use it for same application The application which used to work fine using Revision (240), doesn't work for Revision (305) because ...

Kate Thanks for the description of the usage of ZCLIMATOLOGY. I am doing a full 3D simulation and after reading your reply it doesn't make sense to not use ZCLIMATOLOGY and use some other approach. From the previous methods of using SSH_TIDES, ROMS Tides are neither too big or too small. I have a ma...

Kate Thanks a lot for the reply. I don't plan to nudge to my climatology. I defined "ZCLIMATOLOGY" as cppdefs.h option in my *.h file. I also created an input netcdf file which provides 'zeta_time' and 'zeta' information to ROMS. The model runs smoothly and seems to take information from t...

Hello Everybody I am working on a ROMS(version 3.1-revision-262)-SWAN coupled system based on surf zone environment. Right now I am giving tidal input at the open boundary using a netcdf file and defining SSH_TIDES, UV_TIDES and RAMP_TIDES as my cppdefs.h options. I give all the major tidal constitu...

Hello John I am sorry for asking question related to SWAN on ROMS forum. But the reason for doing that was, I have already done simulations using TPAR file as input for SWAN only and it worked correctly. Problem occurred when I coupled the models. So, I thought maybe the problem occurs because of co...

Hello Everybody I want to use a 'TPAR file' to input wave parameters at one of the boundaries of my ROMS-SWAN coupled system. I tried to define the input file in a standard way (as done in SWAN Model). The ROMS model starts computation, but at the time of coupling the SWAN model doesn't seem to prov...

John I found the error . There was a mismatch between the grid dimensions for ROMS and SWAN grid ( :oops: ). When I change the SWAN grid input file, the model works fine other than blowing up after 10 steps ( :cry: ). I think I will play around a bit with the boundary conditions etc. to solve the bl...

John Yes, INLET_TEST, SHOREFACE work fine for distributed processors (2 for ROMS and 2 for SWAN). But my own application doesn't work. I am checking one of the grid input files for SWAN right now. Let me get back to you after working on it for a while. Thank you for looking into the problem Nirnimesh

Hi John Thanks for the reply 1) I checked the line in Swanparll.F file in Waves/SWAN/Src/ folder. The iopt(ilen) correction has already been done there. 2) I am not using IFORT but PGI compiler. I am using ROMS v 3.0 , SVN revision 240: When I run the previous examples discussed as a part of ROMS Wo...

Hello Everybody I am trying to couple ROMS AND SWAN for a nearshore application like shoreface example distributed with the ROMS code. The program compiles without any error, but when running the executable I get the following error first time: STEP Day HH:MM:SS KINETIC_ENRG POTEN_ENRG TOTAL_ENRG NE...

John Sorry for the late response. I tried the steps you asked me to take and the results are as follows: I changed the boundary condition to EAST_M2FLATHER and EAST_FSCHAPMAN. (a) Using a zero amplitude sine wave at my eastern boundary keeps the model stable. Even if I increase the amplitude to 0.55...

Hello Everybody

Defining RAMP_TIDES as cppdefs.h option, does make the model stable. I am still running the model so will comment on the result after the finish of model run.

Thanks
Nirnimesh

Hello Everybody I am using ROMS (version 3.1, Last Changed Revision -236) coupled with SWAN to measure longshore currents in the surf zone. Since the location has tidal influence and I didn't have any previous experience of using tidal forcing, right now I am just using ROMS(not coupled with SWAN) a...
