WRF-Hydro Model Failure on Large Domain Simulation

[Shanaka Weththasinghe]

Dear all,

I am trying to run the model over a new domain with a watershed area of approximately 10,000 km². However, I am encountering the following error message:

The job is stopped due to the fatal error.  ERROR: Unable to create LDASOUT NetCDF file.  

This occurs when the model is compiled and run with SPATIAL_SOIL=1. When running with SPATIAL_SOIL=0, the model only works on a single processor (or occasionally two) and does not utilize multiple processors.

For context:

• I successfully ran the test case using 32 processors.
• I also ran the model over my previous domain (watershed area: 2,500 km²) with 72 processors without issues.

I have attached the diag_hydro.00000, sbatch script and .log files for your reference.

I would greatly appreciate any assistance or advice on resolving this issue.

Thank you,
Shanaka

Hi Shanaka:

I don't think I have seen this error before. Can you share your namelist files? I always recommend starting with the simplest configuration (spatial soils off, 

all routing components deactivated, idealized forcings... so basically you are running the LSM only and only ingesting the domain & config files), then slowly 

add complexity. If the model does not run under the simplest configuration, then it generally indicates an issue with your domain files or configuration specs.

Thanks!
