WRF model crashed with SBM fast Microphysics with Tiedtke Cumulus physics Scheme

[shahbaz757]

Hi Admin,

I am trying to run the model with SBM fast microphysics and the Tiedtke Cumulus physics Scheme I encountered the model crash. I tried changing and reducing the time_step but that doesn't seem to work in this case.


I am attaching my new namelist file and the latest rsl error files. Please check it out and guide me on what is causing the issue in this case.

Thank you so much.

Does anyone know anything about this issue? I'm seeing the same error message that is in one of the rsl files here (rsl.out.0080):

fatal error in ONECOND1-in (ABS(DAL1*DELMASSL1) > 3.0), model stop

It seems to be related to either excessive condensation or evaporation.

I tried many different things, but I typically receive the above error message within two hours of the simulation time. I tried different temporal and spatial resolutions, input data, different combinations of physics, different dates and locations. The error typically occurs when clouds start to develop. The only time I was able to finish a simulation was in a mostly cloud free case.

Thanks for any insights!
Christian

Christian,
What version of WRF are you using? Can you attach your namelist.input file, and package all your rsl* files into a single *.tar or zipped file and attach that, as well? Thanks!

Thank you for getting back to me.

I am using WRF 4.6.1, but I also tested with WRF 4.2, the version for which the scheme was released but I had the same error.

Please find the requested files attached.

@cplackner
I'm not seeing that same error in your rsl.* files. Additionally, your rsl* files .0000 - .0015 only show using 16 processors (4x4), while the remaining rsl files show that 64 processors are used.

rsl.error.0015: Ntasks in X            4 , ntasks in Y            4
rsl.error.0016: Ntasks in X            8 , ntasks in Y            8

Can you try running this again and then make sure the rsl files you share are all from the same simulation? Thanks!

 

[cplackner]

Sorry, for the mix up with the rsl files.

I recreated the error message with some changes to the namelist. See the attached rsl files and namelist. Hopefully it is correct this time.

Thanks,
Christian

Hi Christian,
Apologies for the delay in response. I still don't see the same errors listed in this thread's initial post. Since your errors are a bit different, can you start a new thread that explains your case, and please attach the necessary files again. Please also let us know if you've made any modifications to the WRF code, or if it's pristine, unchanged code. Thank you.
