Error in real.exe with high resolution using WRF-4.6.0

[peiwang6]

Hi,

I’m running a nested domain with high resolution (9km/3km/1km) using WRF-4.6.0 and WPS4.6.0. The grid points are 1450x1200, 3502x2860, 4666x3301. When I run real.exe, D01 and D02 can generate wrfinput successfully. However, the D03 is always stopped in the middle.

I’m using Intel compiler, and tried to use –O2 and –O1 to compile the WRF4.6.0. The results are always the same. I’ve already set WRFIO_NCD_LARGE_FILE_SUPPORT=1. I attached my namelist.wps, namelist.input, rsl.error.0000, and rsl.out.0000. Do you have any idea why I can’t run D03 successfully?



Thanks!

The grid number is way too large for D03. We are aware of the issue. Currently we can only suggest that you reduce the grid numbers in D03 because we haven't figured out how to solve this issue.

Ok. It seems I have to reduce the grid numbers in D03.
Thanks Ming!

Hi Ming, do you have an estimate that what is the limitation for the grid numbers?

The largest grid number I used before is around 1500 x 1500. Once the grid number is larger than 2000 x 2000, I guess we will start having trouble.
