Ocean Modeling Discussion

Dear all I'm trying to use nudging for my simulation. I used the CPP options TCLIMATOLOGY AND TCLM_NUDGING in my header file to activate nudging. I also created the climatology file and nudging coefficients file. Although I'm able to switch on Nudging for Temperature and Salinity, I get the ...

Hello The options used and the values of input files are not seen in the log. Without that it is not possible for me to figure out what exactly goes wrong and why the blow up. Usually if the speed is above 20 m/s, there will be a blow up which can be adjusted by smoothing the bathymetry and by ...

Dear Dr Wilkin,
I have solved this error. The issue was with the making of initial file and I have rectified it. Now the model is running fine. Me and my team would like to thank you for your valuable suggestions which has helped us in improving our set up.

Dear All I'm attaching the screen shot of my grids made using 25 km resolution for whole NIO with east and north closed and for Bay of Bengal with 9 km resolution keeping east and north closed. I have used the modified ETOPO which most of literature suggests. I have used theta_s and theta_b as 7 and ...

I tried with all of these. now the MODEL runs for 200 time steps and then stops. Could someone tell what could be the possible reasons for the increase in maximum speed. My initial and boundary files seems to be fine and without NaN's. I'm doing the simulation for BoB region with south, west open ...

Dear Sir You have Flather and Chapman OBC on ubar and zeta, and analytical boundary ubar,vbar (in roms_test2.txt) but clamped u,v. Those can't possibly be consistent (i.e vertical average of u,v won't be consistent with ubar,vbar. I recommend radiation on u,v until you get this running. Or ...

Thank you very much for your very detailed reply. I will try these and will post the outcome of my run in the same section. Good day!

Dear All I'm stuck at one point where I'm trying to run a standalone simulation for one month using ROMS_3.7. I have tried two different grids and it is showing diag speed trouble for one grid and a blow up in the first step for the other grid. My DT is 30 seconds. I'm trying to initialise the model ...

I'm getting the following error while I try to compile bio_fennel. Can any one suggest where I'm going wrong? biology.f90(188): error #6689: An assumed-shape array must be declared as a dummy argument.

Could you please try with NCEP GODAS data? You could download it from https://rda.ucar.edu/.

Hi all

I tried two versions of COAWST, however getting the same error while using SCRIP_COAWST. Please help

Hi,

I was able to create the file using touch command with following permission.

drwxrwxr-x 2 student2 research 14848 Jun 6 17:10 .
drwxr-xr-x 5 student2 research 10752 Jun 6 16:03 ..

Yes i have permission for the executable and file. and also for netcdf folder.

Dear all I'm getting this error while running the scrip_coawst. Kindly help ./scrip_coawst scrip_coawst_bob.in ================================================ Read input_file for SCRIP_COAWST Wrapper ================================================ Ngrid_roms= 1 Ngrid_swan= 0 Ngrid_ww3= 0 Ngrid_wrf ...

Thank you, I'm doing it

I tried with cycle length 360 and 365.25 both are causing errors, however, my physical run is successful with the same files. I'm stuck with this error since a long time, so kindly help me.

Can anyone please help me with the run. I'm attaching the screenshot of the error

Can anyone please help me with the simulation over Indian domain using bio fennel? It stops exactly after an year in the climatological simulation. However the same files are running fine with Physical simulation. Please can you help me in this regard?

I'm attaching the ncdump txt of the forcing file. Yes we have set cycle length to 360. I'm facing problem only when i switch on biology, the same files are running fine without fennel. Kindly help me

Hey all, I have given a test simulation with the biological module fennel on, however the model stops at one point each time. I'm getting this error. SET_2DFLD - current model time exceeds ending value for variable: Tair TDAYS = 360.0035 Data Tmin = 0.0000 Data Tmax = 360.0000 Data Tstr = 0.0000 ...

Hello all. I was using Roms AGRIF for doing biogeochemical modelling, now switching to rutgers for the same. Can anyone please help me with the preliminary steps? I created the biundary initial and forcing files using croco tools. However the bio modules in CROCO and Rutgers are not the same. Any ...

How to change the timings of the already tested cases? The ocean_time is 0 and Tair time is 0.5 1.5 2.5 etc

Hello all, i tried to give the test BIOTOY CASE using the fennel module. But I'm getting the following error. Can anybody help?

i gave the run using the command mpirun -np 1 ./oceanM ocean_bio_toy_fennel.in

Hello all, cheers to all of you and wishing you a great day ahead I'm quite new to ROMS model and i have done some test simulations with ROMS-AGRIF. However I'm quite new to ROMS- Rutgers and i would like to run test simulations in BoB region How are the initial boundary and forcing files generated ...
