WRF segmentation fault (signal 11) for 1km domain

[balaji89]

Dear all,

Thanks in advance for your kind help!

I'm wanting to run European windstorm for Europe with major focus over France and Germany.

Brief WRF set-up:

• D3 (9km) : D2 (3km) : D1 (1km)
• Time step = 30s: 10s: 10s/3
• Initial and boundary conditions are taken from ERA5 (~25km and hourly)

I run with below command than runs in 5 CPU with 64 cores each

mpirun -np 320 ./wrf.exe

Problem: WRF runs successful when I run only D1 and D2, but fails in a minute or less when high resolution D3 is included

I very much appreciate your time and support!

the rsl.error.0000 shows the model stops with no error prompting

I am suspicious this is a memory issue. With such a large grid number of 1552 x 1552 x 60, this case will require lots of memory to run.

Can you increase your number of processors and try again? A larger number of processors may give you larger memory.

Please also consult your manager how to increase run-time memory for this case.
