Description
Hi
I am trying to run a 4km model over the Pacific (job xiwhc).
The start dump and LBC are generated by a corser resolution run (job xiwhb) over a larger domain. However the run failed at the 180th timestep with the following message in the .leave file
UM ERROR (Model aborting) :
Routine generating error: GATHER_PACK_FIELD
Error code: 2
Error message:
Error in COEX
and it seems like there's something wrong with all the previous timestep i.e.:
Atm_Step: Timestep (number of timestep)
==============================================
initial Absolute Norm : NaN
GCR( 2 ) converged in 2 iterations.
Final Absolute Norm : NaN
I'm not quite sure what is happening to the run and what's going wrong. Any suggestion please?
Regards
Mike

Hi Mike,
If these are OK, then it is likely that the ancillary files could be to blame.
I notice that you are using an odd number, 13, of processors North and South. You might try 8 or 16 instead.
I hope that helps.
Regards,
Willie
