Hi, I am using CMAQv5.2.1 and my simulation fails on the first time step.
The meteorology for the simulation was generated with WRFv3.7.
I have tried running with the following settings, but each has failed:
- CTM_MAXSYNC = 300, MINSYNC=60
- CTM_MAXSYNC = 240, MINSYNC = 60
- CTM_MAXSYNC = 240, MINSYNC = 15
- CTM_MAXSYNC = 180, MINSYNC = 15
The log for the first day notes that GRID_CRO_2D and INIT_GASC_1 were opened, but:
WARNING in subroutine OPEN3
File not available.
Could not open CTM_CONC_1 for update - try to open new
ERROR: Max number of EBI time step reductions exceeded
*** ERROR ABORT in subroutine HRSOLVER on PE 062
ERROR: Stopping because of EBI convergence failures
When I “grep after log” it seems there are NaNs for HADV, ADV, HDIFF, and DECOUPLE_, and Infinity for CLDPROC.
I have successfully run similar simulations with WRFv3.7 meteorology and the same emissions used here. I have also successfully run similar simulations with the same meteorology on a different computer.
Any recommendations for how to solve this or investigate further?
