Hi,

I'm trying to simulated lightning using WRFV4.1.2.
I can run real.exe well with "lightning_option = 11".
But, if I specify the "iccg_method" to any number,
I would get this error:
Code: 
taskid: 0 hostname: admin
 module_io_quilt_old.F        2931 T
  ------ ERROR while reading namelist physics ------
Maybe here?:      lightning_option                    = 11,
Maybe here?:      iccg_method                         = 1,

If I switch to wrfV3.5.1, I get the similar error when adding "iccg_method":
Code:

I thought there was something wrong with the namelist, but I couldn't figure the exact problem.
Could you help me with this?

Thanks in advance!

Hi Xin,
I was able to run v4.1.2 with your namelist (with iccg_method = 1) and real.exe ran without any problems.
1) Have you modified your code in any way?
2) Did you compile with optimization turned off? If so, what compiler?
 
I'm using the original WRF 4.1.2 codes.
Here's the information about compiler:
Code: 
DESCRIPTION     =       INTEL ($SFC/$SCC)
DMPARALLEL      =        1
OMPCPP          =       # -D_OPENMP
OMP             =       # -qopenmp -fpp -auto
OMPCC           =       # -qopenmp -fpp -auto
SFC             =       ifort
SCC             =       icc
CCOMP           =       icc
DM_FC           =       mpif90 -f90=$(SFC)
DM_CC           =       mpicc -cc=$(SCC)
FC              =       time $(DM_FC)
CC              =       $(DM_CC) -DFSEEKO64_OK
LD              =       $(FC)
RWORDSIZE       =       $(NATIVE_RWORDSIZE)
PROMOTION       =       -real-size `expr 8 \* $(RWORDSIZE)` -i4
ARCH_LOCAL      =       -DNONSTANDARD_SYSTEM_FUNC  -DWRF_USE_CLM
CFLAGS_LOCAL    =       -w -O3 -ip #-xHost -fp-model fast=2 -no-prec-div -no-prec-sqrt -ftz -no-multibyte-chars
LDFLAGS_LOCAL   =       -ip #-xHost -fp-model fast=2 -no-prec-div -no-prec-sqrt -ftz -align all -fno-alias -fno-common
CPLUSPLUSLIB    =
ESMF_LDFLAG     =       $(CPLUSPLUSLIB)
FCOPTIM         =       -O3
FCREDUCEDOPT    =       $(FCOPTIM)
FCNOOPT     =       -O0 -fno-inline -no-ip

BTW, if I set WRF_CHEM=WRF_KPP=0, it works well.
Did you try without chem?

Then, I tested WRF 3.9.1.1 and WRF4.0 with WRF_CHEM=WRF_KPP=1.
The iccg_method works well.
Is there anything changed in WRF 4.1.2?
 
Hi,
I have moved your topic to the WRF-chem section of the forum. Since this works okay without chemistry turned on, then it seems to be related to the chemistry code. Hopefully someone who is experienced with WRF-Chem will be able to help you.
 
Hi, this issue is posted on GitHub now: https://github.com/wrf-model/WRF/issues/1021

Hope it could be fixed soon.
