coawst runs but logs don't grow

[arief121]

Dear all,

I tried to create a simulation by modeling the JOETC project by coupling the WRF+ROMS+SWAN model. The planned simulation is for 3 days with each timestep WRF=54s; ROMS=27s; SWAN=270s.

coawst can be compiled and produced coawstM. when coawst is executed, the model runs until the 130th timestep. the model writes :

that is the last line I got from the log file. I tried to check through slurm, the job model is still running, but the lines or text in the log file are not increasing.

Does anyone can help or have experience and information related to the problem I am experiencing? I've also attached the coupling.in, coupling.h, wrf.input, roms.in and swan.in files that I used in the simulation so you can see what I did to the model.

Thank you. Arief sunda_couple_log.log

thanks for providing all that info. i see "Max map factor in domain 1 = 1.01. Scale the dt in the model accordingly." ...

The "Timing for main" is WRF. And WRF is adjusting the time step for each time. So the models will not come together at the same time for the coupling. We need to have the models all get to the same model time for the coupling.

can you set use_adaptive_time_step = .false., in the wrf namelist and try again?

[jcwarner-usgs]

it is better now. the models exchange fields at the correct intervals.

you have wrf set to only run for 12 hours

run_days = 0, run_hours = 12, run_minutes = 0, run_seconds = 0,

that is what it did. change those run values in the namelist.input. -j

Hi John, thank you for your response.

I already set the use_adaptive_time_step = .false., and I run the coawst again. but I still got the same message in the log file (d01 2022-12-29_12:00:00 wrf: SUCCESS COMPLETE WRF) and the log doesn't write a new line anymore but the model still running like the previous one. Do you know why? or do I have to recompile the model to get the new coawstM after I change the adaptive timestep in the namelist.input? I also attach the last log file after I change the adaptive time step into false.

thank you.

Hi J, thank you

yes, the model is running well now, and yes I realized that some of my WRF settings were wrong and changed it to 2 days. another question, can I run coawst with 3 domains in one simulation? Are there any special settings that I have to do if I want to simulate using 3 domains at once? because I see in the sandy case, it only uses 2 domains.

Arief

[jcwarner-usgs]

it should work for 3 domains. i have had people do this. it just needs a different scrip file, and you need to add columns in the namelist.input.

[arief121]

Hi J,

good news, now I can run a simulation with 3 domains, although the ROMS model is still blowup, but this is a good achievement in my opinion. thank you for your help.

Question, can I set the coawst model to run a simulation using different domain for wrf and the ocean? For example, WRF uses 3 domains, but the oceans (ROMS and SWAN) only use 2 domains, and are coupled in COAWST in one simulation. is it possible to do?

Arief

[jcwarner-usgs]

yes you can do wrf 3 domains, and 2 for roms and 2 for swan. suggest you keep the roms and swan domains the same. those physics are on the same scale. but you can do different size and number of wrf grids than the r+s grids.
