Re: passive tracer: decay term added but not working

Hi John, Thanks for replying. I checked the step3d_t.f90 in build directory and 'tracer_test' piece is present there. The rhs term (source or decay) does not seem to work. I ran two cases, one with tracer_test and one without tracer_test and I am getting the exact same output. my dt(ng) is 15 second...

passive tracer: decay term added but not working

Hello, I want to add a decay term to the passive tracer equation: dC/dt = <diffusive terms> - \alpha*C here, C is concentration of the passive tracer, dC/dt is the material derivative, <diffusive terms> are the diffusive terms, and \alpha*C is the new term I want to add where \alpha is the decay rat...

passive tracer: how to release them after certain period?

I am simulating with 8 passive tracers (dye_01 - dye_08). I need to release them not at the same time but after interval of say 2 hours. So dye_01 will be released at t=0, dye_02 at t=0+2 hrs, etc etc. The only way I know right now is to do it manually, i.e. save a restart file every 2 hrs, give the...

Re: passive tracers - segmentation error ......help? :(

I added the code LDFLAGS += -L/location_of_libcurl -lcurl and it got rid of the 'lcurl' error which I was getting while compiling in the debug mode. Thanks Kate for this suggestion. Debug mode compilation still was not successful due to some other error. Anyways I went ahead and compiled with MPI ==...

passive tracers - segmentation error ......help? :(

Hello! I have a working version which uses external forcing files (wind, BCs, rivers, ...) On top of that I wanted to simulate non reactive passive tracers. So I added variable 'dye_01' to initial conditions netcdf file, with the same dimensions as that of temperature. and in the cpp file (.h) file ...

INQUIRE - unable to find requested variable: tide_period

Hello! I am running the latest version of roms (downloaded fresh copy today and ported everything from older version to newer version. I also ran the test case 'upwelling' and there was no problem in running it.) For the model I am running, I have compiled it with no issues. But when I am running it...

Regarding the option TIDENAME

Hi, I am a new user and I am confused about one option in the ocean.in file. If I have to specify tidal forcing, should I specify it under FRCNAME = ...... by switching off the options SSH_TIDES, UV_TIDES and RAMP_TIDES OR switch on the options SSH_TIDES, UV_TIDES and RAMP_TIDES and specify the tida...

Re: Error while executing Fjord Tidal Case

Hi Kate, I changed the Lm and Mm as per my grid file and the issue was resolved. Now the Fjord tidal case is running without any errors. I guess the lesson I learned is that when the grid is analytical grid, Lm and Mm can be changed in the input file but when external grid file is being called then ...

Hi All, I am new to ROMS and I am trying to get my hands "wet" with it. I am trying to run the Fjord Tidal Case given here: https://www.myroms.org/wiki/FJORD_TIDAL_CASE Although I have the oceanS (or oceanG) file, after issuing the ./oceanG < ocean_fjord.in command, I get the following error: ______...
