Hello,
We are running a 30 km resolution simulation in the WRF model for the Ottawa, Canada region for the time-period: June-August 2018. The model is forced with boundary conditions from North American Regional Reanalysis with spatial resolution of ~33 km. In the simulations, we are using the multi-layer urban model BEP as the urban physics scheme.
When running the model, the pre-processing programs i.e. geogrid, ungrib, metgrid are performed successfully. The real.exe ran successfully but the error occurred on the first time-step when running wrf.exe.
The WRF version is 3.9.1.1.
Major settings in the simulations are as follows:
1) Only one domain is used in this simulation. The number of grids in x and y directions are 100 each (total number of grids in the domain is therefore 100,00).
2) The cumulus parameterization for the domain is set to Kain-Fritsch scheme (cu_physics=1)
3) Time step= 45
4) Urban parameterization: the multi-layer urban model BEP (sf_urban_physics=2).
Other settings are provided in the attached namelist files.
The error message as also provided in the attached rsl.error file is:
WRF TILE 15 IS 97 IE 98 JS 14 JE 14
WRF TILE 16 IS 99 IE 100 JS 14 JE 14
WRF NUMBER OF TILES = 16
[ib7-sln07p08:581 :0:631] Caught signal 11 (Segmentation fault: Sent by the kernel at address (nil))
The model is bring run on our cluster using a total of 5*64 (320 cores) and we also tried 78*16 (1248).
The log files (rsl.* and wrf.log), namelist files(namelist.input, namelist.wps), URBPARM.TBL, job and bash files are attached.
Can you please advise how we can resolve this problem.
Thanks!
