Hi all,
I have been trying to run CMAQ using four nested domains in Brazil, and the multi-day simulations have been displaying a Warning message on Read BC subroutine:
>>—>> WARNING in subroutine Read BCs on PE 000
Applying fix to aerosol Boundary Conditions for aerosol modes. Turn on verbose_rdbcon preprocessor flag to learnmore.
Even with the warnings, coarser domains (d01 and d02) simulations have completed succesfully, The following domain (d03) returns a MPI Abort and forrtl: error (78): process killed (SIGTERM) message in the second day of the simulation:
Maximum eddy diffusivity of: 366.54 (m**2/sec)
at col, row, layer: 22, 12, 14
corresponding to a free tropospheric wind shear of: 1.46485E-03 (/sec),
a bulk Richardson Number of: -101.27 ,
and pot. temps. in layer and layer+1: 311.70 311.95

MPI_ABORT was invoked on rank 1 in communicator MPI_COMM_WORLD
with errorcode 1074146265.
NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Could you help me understand what is causing that warning in the Read BCs subroutine and how can I address it? Additionally, is it reasonable to assume that this warning is the cause for the process killing?
The CTM_LOG* from the d03 domain finishes with the following error:
>>—>> WARNING in subroutine Read BCs on PE 001
Applying fix to aerosol Boundary Conditions for aerosol modes. Turn on verbose_rdbcon preprocessor flag to learnmore.

I would greatly appreciate any insight into how I should treat this occurence.
Thank you!
