CBLAST with SWAN_COUPLING

#1 Unread post by nganju »

I successfully compiled and ran TEST_HEAD and INLET_TEST with waves-ocean coupling. I also successfully compiled and ran the CBLAST application, without coupling. I also ran CBLAST with SWAN alone, no problems.

I compiled CBLAST successfully with SWAN_COUPLING activated, but when I try to run the application, ROMS initializes and SWAN begins computations, but the wave fields never get sent (e.g. TEST_HEAD output like this isn't there...

Code: Select all

== SWAN sent wave fields and Myerror=            0
 Wave-Ocean models coupling, receive                           t=       0.0135
 Wave-Ocean models coupling, send,                             t=       0.0135
 == SWAN recvd ocean fields and Myerror=            0
Then it looks like ROMS is sitting there, patiently waiting for data, before it begins. See output below (I killed the process after a few minutes)...

Is it possibly a time-stamp problem? In ocean_cblast.in I changed DSTART to 12426 (timeref=-2) which should correspond to 5/31/2002 (I also changed timestamps in all forcing files). I have SWAN doing computations starting on 5/31/2002. I have tried other timespans for SWAN, with the same result. Any ideas are appreciated...

This is the old version of the coupling. Notice that ROMS has been updated to standardize the coupling with the MCT library, :arrow: ticket 144 and the SWAN model was updated to the latest version 40.51, :arrow: ticket 146.

I recommend you to update your code to see if you still have the same problem.

I updated to release 177, and now compilation fails...

Code: Select all

cd Build; ifort -c -O2 /align /G7 /MD /Ox -I/cygdrive/c/ROMS/MPICH2/include init
ial.f90 /object:initial.o
Intel(R) Fortran Compiler for 32-bit applications, Version 9.0    Build 20050430
Z Package ID: W_FC_P_9.0.018
Copyright (C) 1985-2005 Intel Corporation.  All rights reserved.

initial.f90(31) : Error: Name in only-list does not exist.   [OCN2WAV_COUPLING]
      USE ocean_coupler_mod, ONLY : ocn2wav_coupling
------------------------------------^
compilation aborted for initial.f90 (code 1)
make: *** [Build/initial.o] Error 1
I have the latest MCT release, installed outside of the ROMS directory. Is it critical to use the MCT release distributed with ROMS?

What application are you running?

This a good example of the compilation errors that users can get when using ROMS. Users need to be curious, read carefully the compiling errors, and track it:
initial.f90(31) : Error: Name in only-list does not exist. [OCN2WAV_COUPLING]
USE ocean_coupler_mod, ONLY : ocn2wav_coupling
------------------------------------^
compilation aborted for initial.f90 (code 1)
make: *** [Build/initial.o] Error 1
It tells you that the problem is in initial.F. The compiler cannot find ocn2wav_coupling in the module ocean_coupler_mod. This module is located in file Mater/ocean_coupler.F. If you don't know where that file is located, just do a grep in the Build directory:

Code: Select all

cd Build
grep ocean_coupler *.f90
ocean_coupler.f90:      MODULE ocean_coupler_mod
ocean_coupler.f90:      END MODULE ocean_coupler_mod
Then, go and find ocean_coupler.F in the source code directory tree. If you check this file, you see something like:

Code: Select all

# ifdef SWAN_COUPLING
#  include "mct_roms_swan.h"
# endif
# ifdef REFDIF_COUPLING
#  include "mct_roms_refdif.h"
# endif
# ifdef WRF_COUPLING
#  include "mct_roms_wrf.h"
# endif
You will see that the routine ocn2wav_coupling is included in file mct_roms_swan.h. If the compiler cannot find this routine is because it was not included during C-preprocessing. Probably, there is nothing at the bottom of ocean_coupler.f90. Did you activated SWAN_COUPLING :?:

Notice that in a previous :arrow: post. I mentioned that you need to have the following in your header file:

Code: Select all

#define SWAN_COUPLING
#ifdef SWAN_COUPLING
# define MCT_LIB
#endif
Mostly all the time, we see a print out of the compiler errors posted in this forum. The errors sometimes are very clear. Users need to be a detective and track them to see what they may be doing something wrong. We do our best to test all the new features that we add to ROMS.

Hello Hernan-
Thanks for the information; I try my best to troubleshoot before posting to the board. I don't expect to have my problems solved by others, I only want to share the information in case others duplicate the problem.

In the original post, what is odd is that TEST_HEAD and INLET_TEST run fine, but the CBLAST application did not (which I ran successfully as separate ROMS and SWAN runs). This was CSTM revision 1498, with MCT v2.5.

With the revision 177, I get "47 unresolved externals" when compiling TEST_HEAD, INLET_TEST, and CBLAST (with #define MCT_LIB added). They are all MPI or MCT-related. I had a previous post about this same problem, which was resovled when I went to the version mentioned in the above paragraph.

I am now totally confused about how to proceed, because other posts suggest that r166 was stable with SWAN, but the current revision is not (e.g. viewtopic.php?p=2815)

I think that the problem is yours. If you are having problems with the MPI and MCT libraries, this is very trivial. The compiler is not finding those libraries :!: It is as simple as that. This doesn't have anything to do with ROMS source code but your compiling configuration file (Compilers/*.mk) and the full path for those libraries. Recall that this are user adjusted file. There is plenty of information about this in :arrow: wikiROMS.

The compiler always gives you the library paths during compilation. Check. You can check if that library path actually exist in your computer.

I ran all these coupling test cases with no problems. I did a correction but that was related to a compiler bug. I made the code more robust to about this error with IFORT.

Re: CBLAST with SWAN_COUPLING

#7 Unread post by nganju »

Just to update, my problem (for both versions of the code) was that I had commented out the matlab file output commands (BLOCK) in the SWAN input file. Apparently those output commands must be specified for SWAN to pass information to ROMS.

One additional note: SWAN's begin time is not considered when the models are coupled, they both begin running and coupling at the same time. All that is considered is the time step and coupling interval.

One more note: Regardless of your SWAN convention for directions (nautical vs. cartesian), wind vector components (as with water currents) are always cartesian: the direction the vector is pointing.
