Hi,
The parameter "diff_6th_opt" in the session of &dynamics need to be set for each domain. For your case, it should be:
diff_6th_opt = 0, 0, 0, 0, 0,
Thanks.
Feng

Hi
I have been trying to run WRF with 5 domains. Even though the real.exe runs successfully, the following errors come for the inner most domain the the mpi run exited. The errors are like as follows:
--------------------------------------------------------------------------------------------------------------------------------------------
forrtl: severe (174): SIGSEGV, segmentation fault occurred
