WRF-Chem stopped writing output but not failed

[mazzeoa]

Hi All,
I'm trying to run WRF-chem with two domains: d01 at 10x10 km (e_we x e_sn 260x260) and d02 at 5x5 km (e_we x e_sn 217x257) for a monthly period. I have correctly run the model for meteorology only and chemistry for the first domain. When I introduce the second domain I can do real.exe without problems but then once in wrf.exe the program stops writing the first wrfoutfile of the d02 domain at this point:

Timing for wrf_ext_write_field: 0.00524 elapsed seconds
<stdin> writing 2d real shdmax
date 2019-07-01_00:00:00
ds 1 1 1
de 216 256 1
ps 1 1 1
pe 108 128 1
ms -4 -4 1
me 118 138 1
d02 2019-07-01_00:00:00 module_io.F: in wrf_write_field

No error from the model that doesn't crash at all but going to see the wrfout_d02 file this seems corrupted considering I cannot enter the file using ncdump.

The namelist I'm using is attached to this message. Is there any way in which I can understand the problem besides the increase in debug level? Is there something I can change in the domain size that could solve the problem? I simulated the meteorology 1 node with 64 cores and tried to increase the number of cores up to 256cores for the chemistry but I always have the same issue.

I hope someone can help with this issue.
Many Thanks in advance

Hi,

Please provide an rsl.out/error file with an increased debug level. You may also try setting chem_opt = 0 for both domains to rule out some processes.

Hi Jordan,
thanks for your answer. Sorry if I reply only now but asking advices also to the internal IT service they asked me to recompile WRF using different options. I'm attaching to this email the rsl.out/errors of the real.exe process that performs fine (rsl.zip folder). After running real.exe I launched wrf.exe and I get the same error. I'm attaching also the rsl.out/errors for the wrf.exe run (wrf.rsl.zip folder). I set chem_opt = 0 in this test as suggested.

Thanks for the help

Just an update.
I have recompiled the model using version 4.5.2 and using the following libraries:
using:
gcc.8.2.0
with:
zlib.1.3
HDF5.1.14.3
netcdf-fortran.4.6.1
netcdf-c.4.6.1
jasper.1.900.1
libpng.1.6.39
mpich 4.0.3

I sent a simulation using the namelist I attached in my first message and both real.exe and wrf.exe run well. I'm currently running the model with the chemical options activated.

It seems that the change of version solved the problem.

Which version of WRF were you using before @mazzeoa ?

 

[mazzeoa]

I was using WRFv4.5

I was using WRFv4.5

@mazzeoa glad to hear the upgrading fixed it
