Hi everyone,

I have recently tried commenting the chemall sections in the mod_che_chemistry.F90, as suggested by Ahmed. 


          ! 1 : initialise xrin with the concentrations from
          !     previous chemsolv step
!          do ic = 1 , totsp
!            xrin(ic) = chemall(j,i,k,ic)
!          end do

and

          ! save the concentrations of all species for next chemistry step
!          do ic = 1 , totsp
!            chemall(j,i,k,ic) = xrout(ic)
!          end do
          ! Store photolysis rates for diagnostic

Dear Ahmed,

The simulation has just run to completion this way. however, I am concerned that this way, there is no chemistry continuity between time steps. It this the case? if so, how can we resolve this? 

Best regards,
James

Hi James,

We try to run the recent version also with CBMZ or DCCB and we get this error also.
The file of regcm.in and the error message are in the attachments.

Best regards,
Zeinab

الموضوع: [RegCNET] CBMZ chemistry crash

Dear RegCNETers,

I have installed a recent version of the RegCM and tried to run a CBMZ simulation for 1 year. However, the chemistry crashed and the simulation kept on running producing a massive error log.

After including a few lines in the mod_che_chemistry.F90 I got the following information on when the error is happening:

xrout, xrin, trac%indcbmz
  7.864835401599373E+153   38524086126.5782               10

10 is H2O2.

I have attached the regcm.in file and the error obtained. I cannot figure out why this is happening. I was wondering if anyone has any idea on the matter. 

Thanks and regards,
James
