Ocean Modeling Discussion

thank you so much for your response. I am using ROMS AGRIF for sediment transport modeling.

I have pointed out the problem of the grid stiffness ratio, in my previous simulation the hmin=75 but in the last post where the stiffness ratio is showing **** the hmin= -2504.7962.

Hello Previously I Have run the model but this time why stiffness ratio is not coming into some decimal numbers? I am very much curious about it or if I have missed the correct stiffness ratio files. Regard and thanks. N_BOB 8640 ntimes Total number of timesteps for 3D equations. 300.00 dt Timestep ...

I was also thinking after getting the error that I should add the sediment parameters into the restart file because those parameters were added in the initial file. it is an inter-annual simulation for which I am looking. I have run a climatological simulation with those parameters already added ...

I am trying to run inter annual simulation for my area of study by coupling ROMS-CSTMS. I Have completed a climatology run for the same area but got the error when performing inter annual run. NUMBER OF THREADS: 1 BLOCKING: 1 x 1. sediment inputfile sediment.in not found sediment initialization from ...

hello
better if you can contact the developer JC warner, he will tell you more in detail.
thanks!

Hi
You need not to add anything instead of that the variable which is not required for simulation should be keep #undef in your cppdef.h (header file).

Hi
you should individually keep #undef all variables as you mentioned e.g grain_diameter, erosion_stress, ripple_lenght etc.

Hi
If you do not want to look for sediment related variables then you should keep
#undef SEDIMENT in your cppdef.h file.
hope this will help you.
thanks!

hello I am saving the data into history and the average files after 5 days (ie. 1440 time steps) but when I reduced the time steps 288 (Daily) to save the variables (bed_frac_sand and bed_frac_silt) the model is writing the variables into history and average files at different time steps (288,576 ...

hello I am running ROMS model with activate sediment module for 10 years climatology simulation, after completing 1440 time step the model showing error in writing history and average files. suggest me solution, please. 1437 4.98958 2.074203283E-01 9.8209920E-01 1.1895195E+00 1.4316434E+15 0 1438 4 ...

thank you sir for your valuable and quick response.
I checked the dimension of bed_thick which is ok but did not chek the NLAY = 2 (default in the model package) in param.h. I have defined Nbed=1 in nc file and I changed it to NLAY=1 in param.h file, after that the model is running properly.

After adding the required variables in roms_ini.nc (ie. sand, silt, bed_thick, bed_poros..........etc) I am getting this error. Maximum grid stiffness ratios: rx0 =0.2368669301 rx1 = 2.3216424860 GET_INITIAL -- Processing data for time = 0.000 record = 1 NF_FREAD ERROR: nf_get_vara netCDF error code ...

ok, I shall upgrade it to ROMS 3.7, Thank you so much for your valuable information.

I am working on sediment transport in the coastal zone of the Bay of Bengal using ROMS+CSTMS coupling. so I have activated the sediment module.
Thank you.

I have a Linux operating system, ROMS (V3.1.1).

yes, I applied a simple case to test the model but any other thing need to run it. Does a wave model need to activate?

Hi Actually, I am studying sediment transport modeling using ROMS. the sediment module CSTMS has been implemented in ROMS. I activated the sediment module by the following in cppdef.h file. # undef BIOLOGY # undef FLOATS # undef STATIONS # undef PASSIVE_TRACER # define SEDIMENT # define BBL I have ...

hello sir during compilation i am getting this error. the model is running and unable to write the sediment properties and its value in the history and average file...it may be due to the absence of tile.h file. thanks in advance. ana_sediment.h:27:0: fatal error: tile.h: No such file or directory ...

Thank you so much for your vital response, I am new in sediment transport modelling using ROMS.

Hi I am a new user of ROMS, working on sediment transport modelling in Odisha coast of Northern Bay of Bengal. I have made all the initial file including grid, forcing, bulk, clim, boundary files. when I am running the model by giving command ./roms roms.in I am getting the error in roms_ini.nc file ...
