ASTEM internal time step exceed error

Post by Diljeet35 » Thu Jun 17, 2021 1:42 am

Hello,
I am facing an internal time step exceeding error(fort.67) each time when I am running with chem_opt =202. The optimization level of my chem is -O1. I am running wrf.exe on intel compiler. Version is WRF-Chem V3.8.1. Using Mozart in MOZBC as boundary conditions.

2nd issue is should we use chem_in_opt =1 while using mozbc to update the boundary conditions in the wrfinput and wrfbdy?

It will be a great help if somebody rectifies it. I do not want to recompile module_mosaic_therm.F by changing the default setting of the model unless recommended by the experts in this panel.

Attaching the namelist file for the referral.
