WRF-Chem Model Error: SIGABRT and Segmentation Fault Issues

Hello everyone,

I am running the WRF-Chem (4.4) model and have encountered several issues that I hope to get some assistance with. Below are the details of the errors I am experiencing. The relevant files are also attached for reference.



munmap_chunk(): invalid pointer

Program received signal SIGABRT: Process abort signal.

Backtrace for this error:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:


And in rsl.out, the message is

in above message, i1 =-391202822
*** module_cmuaq_bulk, aubr aqintegr1 -- svode failed, istate = -3
*** mosaic_cloudchem_driver, subr interface_to_aqoperator1
id,it,jt,kt, istat_fatal, warn = 1 28 21 4 -10 0
dvode-- maxord (=i1) .lt. 0
in above message, i1 =-391202822
*** module_cmuaq_bulk, aubr aqintegr1 -- svode failed, istate = -3
*** mosaic_cloudchem_driver, subr interface_to_aqoperator1
id,it,jt,kt, istat_fatal, warn = 1 28 21 5 -10 0
leaving mosaic_cloudchem_driver - ktau = 1 3



As this seems to be a processor issue, I have tried several options such as 4, 8, 16, or 32 processors, but ended up with the same results. Also, I have enough memory in my system (more than 4TB). As I am a beginner, I guess I am committing some mistakes while setting up the namelist, or it can be something else that I might not be able to figure out.

Any guidance or suggestions on how to resolve these issues would be greatly appreciated.

Thank you in advance for your help!
Sanatan.

I would double check your timesteps and start end date.

Right now it looks like you have a 500sec time step which is enormous and a outer domain of 100km grid space.

also could you please upload your namelist.wps file?
 
Thank you very much William for your time.
Here I have attached namelist.wps file to this message.

Additionally, I should also tell you that when I tried chem_opt=301 and dust_opt=1, the model ran successfully. The namelist with a successful run is also attached to this message named "chem-301-namelist.input".

@William.Hatheway, For chemical boundary conditions, I am using WACCM data (i.e., waccm-20240628124350715760.nc), and for meteorology I am using fnl data. Attached is the namelist used in MOZBC.
