Ocean Modeling Discussion

Dear ROMS users,

Has anyone compiled ROMS adjoint using gfortran compiler? The following errors appeared,when I try to build it using gfortran and openmpi. I can compile and run ROMS Nonlinear model successfully with this fortran compiler.

tl_set_vbc.f90: In function 'tl_set_vbc_tile':

Hi, Kate. Thank you for your explanations ,which help me remove my misunderstanding of this problem.

Dear all,

I ofen see ' ROMS is an Eddy-resolving model ' from various of paper , but I don't know how to judge a model if it is a eddy-resolving model.
What unique charateristic and function does an eddy-resolving model have? Any information are greatly appreciated .

Hi, everybody:

I find cosine values of grid corners should be less than 0.02 in offshore areas for Delft3d, that means grid corner's angle should be bigger than 88.85 degree. So what is orthogonality requirement in ROMS ? Thanks.

My model blows up at 1494, but I can't find any problem from rst file. So I rerun this model from the restart file without changing other input files like forcing files and bry files, it can run successfully. Could anyone tell me why this happened?

The First Run:

Thank you so much for your help, Dakui. I will try it following your kindly suggestions and then present the new result as soon as possible.

Hi,yang. I can only answer your second question as I have few experience of modelling,especially of ROMS.

Hello All!

I want to setup my first application by using climatological forcings(ECMWF wind and COADS heat flux) and boundary conditions(SODA). My physical and numerical settings are as follows:

Activated C-preprocessing Options:

Hi,everyone.

Recently,I have succeeded in configuring an simple application of the forward simulation using ana_*.h . But I have trouble with creating netcdf files such as initial files and forcing files , because I am not very clear what variables to be given values. So I want to read the source ...

Hi ,everyone.
What optimal method used by ROMS to adjust the control variable to minimize the cost function ? which procedure to compute the optimal direction towards the minimum of the cost function and the step size in that direction?
Thank you very much.

Hi,Kate. Thanks for your reply.

Sorry,I am not quite sure about what do you mean by

We have the CORE forcing files beat into shape

Hello,everyone.
Recently,I was trying to compile the forcing package in Fedora 7 . I have modified CFT and LDR in Makefile.Gnu as follows

Hi, I was trying to build Nemuro ecosystem test ,but I didn't find nemuro.h in ROMS/Include. Then I copied nemuro.h from ROMS/Nonlinear .

I activated NEMURO cpp option in the makefile and typed the command

Hi ,arango ,Kate
Thank you very much for your replies,which really help me a lot

Thank you very much for your constructions, m.hadfield.
When I compiled the OMP ROMS and typed this command:

make -j

I got the following warning:

make: warning: Clock skew detected. Your build may be incomplete.

I don't know what caused this problem in general.

I know few about OpenMP ...

Hi,jcwarner
Thanks for your reply.
When I typed this command:

make -j > compile.txt

I got the following message:

Hi,
I turned on shared-memory parallelization in ROMS using the OpenMP compiler directives in SGI workstation with ifort compiler in the upwelling test. It runs fine on SERIAL.

I typed the following command :
make -j 8 > compile.txt
then I got the following warnings:

Thank you very much for your instruction.

Hi, m.hadfield ,Kate,
Thanks for your reply . It is indeed the problem of the compiler .
By the way ,how do I know what compilers my Operating System has installed and which version they are.
Thank you.

Thanks to jcwarner ,gerardo and LIn, I have got rid of this problem at last .
It is caused by the netcdf . Thanks again for all your support.

Hi jcwarner
Thanks for your reply.
After trying ' chmod +x cpp_clean ' and modifying the lib and include of netcdf,I run 'make' again.

I get the following errors:


zw@a330:~/roms> make
make: svnversion: Command not found
: No such file or directory

Thanks,robertson,I have sent an email to robertson@marine.rutgers.edu to change my username.

Thanks,stef
I have tried type 'Zhou\ Wei' ,but it didn't work.
Have you any other ideas ,thank you .
