Problem with chem_conv_tr

Postby slekaw » Mon Feb 24, 2014 6:50 pm

Hi,

I'm trying to run WRF-Chem v 3.4.1 with no cumulus scheme. Even though I've turned off the chemistry (chem_opt = 0) I still get this message:

"ERROR: chem_conv_tr = 1 requires cu_diags = 1".

I've set chem_conv_tr = 0, cu_diags = 0, and cu_phys = 0. I'm wondering if there is a variable that overrides this chem_conv_tr variable?

Any help is greatly appreciated! Here is my namelist.

I think it may be possible that cu_diag = 1 has been set if you choose cu_physics = 3 or 5; or cu_rad_feedback = .true.. See page 5-67 of the WRF Users Manual, and page 22 of the WRF-Chem Users Manual.
