WRFv4.6.0 crush?

Hi all,

I am facing an issue where WRF crashes at the first time step.
I would greatly appreciate any help you can provide.

I am a new WRF user and have installed the latest WRF model on my Linux server.
I successfully ran a test following the instructions here:

Now, I am moving to the next step to run the event I am interested in.
I successfully created the initial and lateral data from ERA-5, and then I ran WRF.
My run outputs data at the initial condition, but the run crashes while calculating the next time step.
My namelist, rsl.error, and rsl.out are attached.

Thank you in advance,
Masaru

Masaru,

This case failed immediately after wrf.exe started, indicating that this is either a memory issue or a data issue. There is no error message in your rsl files, which makes it hard for me to determine what is wrong. The good news is that your namelist.input looks fine.

The namelist file shows that you are running with triply nested domain, which is way complicate for a beginner who just started learning WRF. I would like to suggest that:

(1) run over a single domain first
(2) use the relatively "easy" data, i.e., GFS, to drive WRF

You can download GFS data from NCAR RDA Dataset ds084.1, and use Vtable.GFS to ungrib this data.

Would you please try this case but over a single domain and use GFS as input? Please let me know if you have any issues.
 
Hi Ming,

I apologize for the late response. I followed your advice, but the run stopped, as well.
After all, I reinstalled WRF again, and then it worked well, including the run with 3 domains and ERA-5.

I appreciate your help,
Masaru
 
Masaru,

Thanks for the update. I am glad it works for you. So the issues you have before are caused by obsolete wrf.exe, I guess.
