coawst model without any output

[pike-hhh]

When I run the coupled model of WRF, SWAN, and ROMS for a month, I found that the model does not terminate and produces no output except for two lines stating "Coupled Input File name = Projects/cangnan/coupling.in". However, when I debugged using a two-day simulation, it ran normally and produced results. The only thing I changed was the input files corresponding to different time periods and the time settings in the .in file. Now, I'm encountering this issue. Does anyone know what might be causing this? Please help.

you need to look at what is different. something is different.
did you get and Err* files from swan?

[pike-hhh]

Didn't produce any Err*

[jcwarner-usgs]

i am not sure. one of the models is not getting the correct info.
can you do a diff on the input files to see everything that was changed?
make sure you do not have any TABs.

I believe the model is not actually starting to run. I have tried the following: First, I changed the name of the .in file, and the model ran normally but reported an error saying it could not find the corresponding file. However, when I input the correct file name, this problem arises. Second, I changed the number of cores, causing it to mismatch the setting in the .in file. At this point, the model still runs but does not report any errors or produce any output.

[jcwarner-usgs]

when you changed the number of cores, you say the model 'still runs' . what does that mean?

[pike-hhh]

For instance, if I define the use of 64 cores in the namelist but only specify 4 cores in the coupling setup, theoretically, there should be an error message. However, there isn't any, and the model continues to run but produces no output.

So I believe that the model has not correctly read the coupling.in file.

[jcwarner-usgs]

can you show me the stdout from the model?
how are you launching the model?

this is my coupling,in , the strange thing is that when I debugged using a two-day simulation, it ran successfully and produced results.
coupling.in.txt

The remaining .in files are provided below.

i do know that swan does not like long file path_names
&READINP WIND 1 '/share/home/herongyu/models/COAWST_al/COAWST-temporary/Projects/ss_demo/nest_FNL_Feb2022.dat' 4 0 FREE
that might be too long. can u move the file or link it to the current dir and try that?
maybe even for the coords and bottom files, for both input files.

did that work before?
what are the permissions on the coupling.in?
