CROCO+WRF+OASIS
Up to Specific issues in real coupled models
Posted by Anonymous at June 10 2025
Hello,
I am trying to couple CROCO and WRF through oasis, but the run either freezes, either fails.
The run command is "mpirun -np 4 ./wrfexe : -np 4 ./crocox croco.in"
There is nothing in the output file, even no debug or nout.000 files.
There is only rsl.error.000x files and rsl.out.000x files. And the rsl.error.0000 shows:
taskid: 0 hostname: w-virtual-machine
module_io_quilt_old.F 2931 F
I did two steps to make sure the WRF and CROCO are ok.
First, if I run "mpirun -np 4 ./wrfexe". I can get the wrfout.
Second, if I undef OA_COUPLING in cppdefs.h of CROCO and run "mpirun -np 4 ./croco croco.in", I can get the output files too.
I really don't know where to find the errors.
Here is the namcouple:
# NFIELDS: total number of fields being exchanged
$NFIELDS
10
#########################################################################
# NBMODEL: number of models and their names (6 characters)
$NBMODEL
2 wrfexe crocox
###########################################################################
# RUNTIME: total simulated time for the actual run in seconds (

I don't see a $NLOGPRT entry in the namcouple.
If there really isn't one, then it's definitely worth adding one
(probably with a value of 30).
$NBMODEL is deprecated at OASIS-MCT vn3-ish. Does that imply you're using a very old version of OASIS3-MCT?
Cheers,

Hi,
This issue is not related to OASIS-MCT.
It pertains specifically to the CROCO community.
Please post your question on the CROCO forum: https://forum.croco-ocean.org/
You may also find relevant information there.
Best,
