Ocean Modeling Discussion

Thank you robertson and Kate. I have successfully checked ifort compiler with netcdf (3.6.1) and mpich using openmpi for some other examples (test provided by netcdf and mpich packages) but still can not sure the problem. I reinstall the netcdf c and fortran with gfortran then now everything ok. I ...

Thank you Kate for the suggestion
I change to mpif90 then it show this error

Hi all
I compiled I4dvar then try to run it on my laptop core i7 8 threads with 16gb ram. The stdout shows the model run for a short time then stuck at line 28310 with " <<<< Conjugate Gradient Algorithm >>>>". Task manager shows that I have 8 threads are still running with about 12% of cpu and 60mb ...

Dear

I am studying I4dvar and trying to run it's exercises. After compiled the model I run with the default in file "roms_wc13_2hours.in" The model blow up at first time step with log file log_dt1800.txt

As other has suggested that I can reduce the timestep to pass this case problem then I try to ...

I want to try the plot code distributed by source code as it was tested by others. Ncl is good and free and a good alternative way. But up to now I can have only ncl work for post processes. I still want to compile a working roms plotting.

I have the thing done with interesting and nice .gif file results of concentration in minus, continuing find-out why.

I installed NCARG version 662 with gfortran then try to compile Roms' plot then get this error

Iam sr. I have used wrong input

I try to increase the grid resolution of riverplume1 test case by applying my grid.nc which increase from 102x82 to 468x468 then has following error.

Thank you wilkin It worked like a charm.

Need help to build my application base on river_plume test case

So far I've completed several steps

1- run river_plume1 test case;
2- added my own grid-domain to the case;
3- moved the point source position from the border to a point inside the grid. Then run successfully with both LuvSrc or LwSrc ...

Thank you so much CharlesJames ecjoliver. Now i have my grid as your comments.

I compiled and run the I4DVAR with all default cpp.h , input files ... etc. It run then hang with <<<< Conjugate Gradient Algorithm >>>>, the cpu usage still show up but no thing happened.
This is the last log

Thank you arango for your comments.
I has changed the topic as remove the lake_jersey in the title.

Dear
I compiled lake_jersey test case with all default setting in Forward folder then run it with my grid file. It run for nearly 100 steps then blowup, by checking rst.nc file I found up that at some isolated 1 cell bay at the boundary the temp go strange ( minus temp with blue color in the ...

Thanks to wilkin

I corrected as your recommended then the model pass that error. After 137 steps it blowup again. This time it blowedup when the boundary flow reached to an Island in the mìddle of the grid. I checked that Island, it has 1.e37 in h which is strange because I changed it to 10 m depth ...

Thank you jcwarner.
I compiled the romM with default setting of Forward in Lake_jersey folder, then try using my own grid and ini condition (attached .nc files lake_jersey_ini_a.nc lake_jersey_grd_a.nc ). run the default .in file in the folder then Roms gave me this stdout ...

Dear

I am new to roms and trying to run testcases, I compiled lake_jersey and try to run romsM then it gave me this error. As some other topic recommended that with NaN error at first time steps may related to ana_ and input script but I still do not know where to fix. I have already checked the ...

Dear Friends
Thanks for a lots of great works in Roms' forums. I am new to Roms and trying to create a grid with Gridbuilder by CharlesJames. I have created my grid.nc file but when I checked it with ncview I realize It seem to be a bug in Gridbuilder when generating .nc file.

The problem here is ...
