Ocean Modeling Discussion

No problem anymore, thanks

Ther is an error message regarding the variable Ltracing when compiling read_phypar.F. It seems that Ltracing has not been defined in the latest version of roms: https://www.myroms.org/svn/src/trunk $LastChangedDate: 2020-04-27 10:06:37 +0800 (Mon, 27 Apr 2020 ...

Do you know if any of the ice observed there was formed there, or was it all advected southward from outside your domain? I do not have data to determine which source is more important, but I know sea ice is constantly advected from the north. I did not have the boundary condition, because I don't ...

Hi Ufuk,
Have you tried to increase heat loss at the surface of your domain, just to reduce the temperature, and see whether ice can form?

Hi Kate, My area of interest is the Labrador Sea. I attached a figure to be more accurate. I have four open boundaries. I am not sure whether the vertical boundary heat loss or the southward and eastward cold and fresh water (or ice) transport is more important. However, the ice in this region often ...

Hi Ufuk, I have been using Kate's sea ice code too, and did not get any ice except in a very thin boundary layer. I am wondering if you have successfully produced ice reasonably distributed, and how did you do it? I used gradient boundary condition for the sea ice, because I do not have sea ice ...

Hi, I just found out the problem is actually hardware related somehow.
I cannot use all the two threads of each core to run the model, I can only employ 10 cores at the most.

Thanks, Kate!

Hi Kate,
Thank you for your reply. I also tried without the '<', but the result is just the same.

I don't know about runmpi, I do which runmpi, nothing returned.

Hi Kate, The mpi related libraries are located in the /usr/lib directory as I specified. And I did use mpif90 to compile and link "successfully" without errors. However when I use 'mpirun -np 20 ./oceanM < ocean.in', the following errors occur: mca: base: component_find: unable to open /usr/lib ...

Hi all, I am using mac os x 10.6.8 (x86_64), and have gfortran as fortran compiler. I downloaded openmpi and installed it. When I try to compile ROMS with MPI, I got the error message as follows: ======================================================================== /usr/local/gfortran/bin ...
