Hi,

I am trying to run WRF v4.2 with Noah-MP (sf_surface_physics = 4) for 3 nested domains.

The model runs for a few timesteps before producing the following error:

forrtl: severe (154): array index out of bounds

I am able to run WRF fine with Noah LSM (sf_surface_physics = 2) under similar configurations.

Attached is my namelist file.

I appreciate any advice on this.

Thanks,
Ulysse

Ulysse,
Would you please turn off spectral nudging, then rerun this case? This will reduce the complexity and makes it easier to track the problem.
Also, if you run a single domain case, can this case be done successfully?
What is the version of WRF you are running?
 
Hi Ming,

Thanks for the reply.

I was able to narrow down the problem and run the model successfully by changing the number of processors.

This was WRF v 4.2.

Best,
Ulysse

Would you please clarify how you fix the problem? Is it a number of processor issue, or is it related to physics and namelist options? Thanks!
 
Hi,

I thought I had fixed the problem because the model was running without any issues when I ran WRF with a Distributed Debugging Too (ddt).

However, after recompiling WRF to remove the ddt, with everything else set the same, I still get the error:
forrtl: severe (154): array index out of bounds

I have tried removing spectral nudging and running the model only on the most outer domain. The same error shows up, always at the same time in the simulation:

Timing for main: time 2010-12-14_00:04:48 on domain 1: 0.26658 elapsed seconds

EDIT: I have also tried this with both WRF v 4.2 and v4.3 and get the same error.

I'm not sure why it worked with the ddt.

Thanks,
Ulysse
 
Would you please send me your namelist.wps to take a look? By the way, what data did you use to drive this case?
 
Hi Ming,

Attached is my namelist.wps.

I am using ERA5 Reanalysis (https://rda.ucar.edu/datasets/ds633.0/)

Thanks,

Ulysse
