Hi all,

I am trying to run CMAQ v5.3.2-DDM, but I have an issue that the sensitivity coefficients in ASENS outputs are all zero. I successfully run the base simulation using v5.3.2 already so I think there might not be any problem with the inputs. Is there anyone who had experienced such an issue? I would like to know how to fix my run. Thanks!

Note: ACONC, CONC are all successfully simulated with reasonable values on all variables.

Please, try CMAQ v5.4-DDM-3D. The version you are trying is not officially supported for DDM-3D and should produce zero outputs for a lot of the sensitivity fields.
