Ocean Modeling Discussion

Dear Aminrahdarian, kate, and arango,

Thank you very much for prompt reply.

Yes, it is Darwin configuration that needs it. As Kate said, just comment the line in the Linux-ifort configuration file. Linux will take the unlimited value from the environmental variable. It is the loader LD that it ...

Dear Sir or Madam,

I installed the newest ROMS source codes:
https://www.myroms.org/projects/src/ticket/769

that includes the modified "Linux-ifort.mk".

And I tried to MPI compile (make) UPWELLING case using 'ifort'
compiler. The consequences, however, the following error messages
appeared and ...

Dear Kate,

Thank you very much for answering my questions and I am sorry for my
late reply.

Please let me give a time to do 'try and error' with referring to
your advice for a while.

Again, thanks so much for your advice.

Best regards,

Hiroshi

Dear Kate,

I am sorry to have kept you waiting for the answers. Here are them;

Yes, I set NINFO=1 in the input file:"ocean_seto_2010_017.in" (see
attached ...

Dear Kate,

Thank you very much for your advice! Now I am trying to check the
points that you have suggested. So would you please give me a time
for a while to complete all check? I will send (post) the answers
soon.

Again, thanks so much for your useful advice.

Best regards,

Hiroshi

Hello, would you please give me any advice to solve my ROMS blow up
trouble as follows?

I am trying to drive the old ROMS (Version: 3.5 (Last Changed
Revision: 561)) to simulate the ocean condition in the Seto Inland
Sea, Japan.

Input forcing parameters as follows;
*) tidal forcing (effect of ...

What is the value of the the dimension: 'time' on your output (his or

Would you explain more concretely?; how do you want to modify the

If you want to use "Rutger's ROMS", why not referring to
https://www.myroms.org/wiki/index.php/Tutorials ? Or if you want to
use "Penven's ROMSTOOLS (ROMS_AGRIF)", why not ...

Dear all,

I am facing the following trouble when executing LTRANS in case of
using Penven's ROMSTOOLS (ROMS_AGRIF) outputs (history or average
file). Would you please teach me how to fix?;

After succeeding in compiling LTRANS,:

% ./LTRANS_compile.sh

I tried to execute "LTRANS.exe ...

Hi Lee,
Can I make some questions? We need more information in detail;

1) What is version of your MATLAB?
2) Why don't you use (download) the newest netCDF Library: netcdf-4.0.1 so far?
3) I can't understand the meaning of your sentence clearly as follows: "It worked in PC but not in UNIX.". Pls ...

Hi Sriram,

> I would like to write daily averages

You can write down daily averages onto averages file: ".._avg_.." by
setting "NAVG" appropriately. "NAVG" defines the number of timesteps
between writing of time-averaged data into averages file.

To write down daily averages, you can derive "NAVG ...

Hi Sriram, Thanks for uploading the code (input parameter file) you are using.

For example, why not changing the value of "NWRT" from 'NUMTIMES' to '48', which is same as the value of "NAVG", as follows?;

BEFORE (Your Original Code):
..........
restart: NRST, NRPFRST / filename
NUMTIMES -1
ROMS ...

Hi Sriram,

Would you show us the contents (code) of input parameter file: "roms_inter.in" that you are using?
This file also control the number of timesteps between writing of output data.

Cheers,

Hiroshi (hyy)

Hello, ROMS Users,

I am trying to use inert passive tracer by Cpp option:
"PASSIVE_TRACER" on IRD's ROMS_AGRIF
(http://roms.mpl.ird.fr/doc/index.html), that is defined in
"cppdefs.h". But I do not know for sure how to use it. Is there
anyone who can teach me how to use (e.g., files and/or ...
