MOZCART T1 WRF-Chem stops on restart with no errors

[Aara'L Yarber]

Hello all, 

I am using FINNv2.5 for a one-year biomass burning simulation with WRF-Chem v 4.4.1 using MOZCART T1. The initial run will run for about 14 days, but the restart run will stop on the first or second day without any errors in the rsl files. 

I have included my namelist and fire_emis.inp. For debugging, I turned off all chemistry and am only simulating aerosols, but it is still not working. I haven't found any negative values in the wrffirechemi files, and the variables in the wrfout files look normal. I have also tried increasing the time step from 60 to 120, but that did not help. I am wondering if there is something wrong in the namelist that I'm missing. 

Thanks!

Hi Aara'L

in namelist.input set the value for debug_level to a number higher than 0 (e.g. 100) which will give you more information in your log files on why the simulation stops.

Hi Gabi,

Thanks for your feedback. I have tried setting debug to 100, but it just made my rsl files huge with little useful information. I am now finding this message which I think may be a segmentation fault in two of my rsl files:

Hi Aara'L

unfortunately I am not familiar with this type of error but hopefully someone else from the community is able to help.
