ERROR: calc_h2so4_wtpct error

[xyli@geo_uio_no]

Dear all,

I started a simulation with the following compset,

./create_newcase --case /cluster/home/xiangyuli/cases/BW-control-190626 --compset BW1850 --res f09_g17 --machine fram

After running for 34 years and 6 months, the following error occurred,

calc_h2so4_wtpct: invalid activity: activ,qh2o,qs,temp,pres=
NaN NaN 2.009130197760724E-005
140.000000000000 5.960300031304655E-004
ERROR: calc_h2so4_wtpct error

Any idea about this?

Attached please kindly find my CESM log file.

Best regards,

Xiang-Yu

This looks like an error from the cam source code.  You might try posting on the atm/cam bb.

Thank you for observing this.
I have now posted it to the WACCM forum
since the compset is for WACCM.

You are getting "not a number" (NaN) values for some variables used in a calculation. NaNs can result from things like division by zero. The message you are getting is coming from a part of the code that checks to make sure certain variables are reasonable. Something in your run created unreasonable conditions. I would suggest running with debugging flags to check for NaNs and track down the source of the problem.
