Failed to output var into iulog

[CaliFornia]

I'm trying to output a variable (prc_coef) used in this code: E3SM/components/eam/src/physics/cam/micro_mg_utils.F90

I want to write(iulog,*) prc_coef so that the values of this variable can be checked in the log file. However, it seems impossible to add this new line into elemental subroutine kk2000_liq_autoconversion where it is calculated.

I have already added use cam_logfile, only: iulog at the beginning of micro_mg_utils.F90. But this will result in an error when building the model. Anyone have any ideas on this issue? Thank you.

Hello!

What is the build error you are getting when trying to write the variable?

It seems like a syntax error. Info stored in the log file shows this at the end:

My guess is that there is something special needed to be done before writing in an elementary subroutine? Cus I typed use cam_logfile, only:iulog at the beginning of this module code but used write (iulog,*) prc_coef under an elementary subroutine?

Thanks for the info.

From a CESM perspective, the "use" statement and the "write" statement pair you're using should work. Unfortunately, your problem may be specific to E3SM so I would suggest reaching out to someone in E3SM for help.
