Error in SMVGEAR when running CMAQv5.2

CMAQ

Hi all,
I’m using the CMAQv5.2 , The mechanism I chose is saprc07tb_ae6_aq and the gas-phase chemistry solver module is SMVGEAR.However, it shows these following error messages

I have not used SMVGEAR. However, my experience has been that solver errors of this sort are most often indicators that something else has gone wrong, such as species becoming NaN or infinity. Look at the checksums in the log file (grep for “after”) and see if that turns anything up.

This appears to happen at 00:00:00, i.e., the start of a day. Is it the start of your simulation? If so, it is unlikely that you actually have a chemistry problem immediately.
