    WRF RUN ERROR: Program received signal SIGSEGV: Segmentation fault - invalid memory reference

    I'm running WRF452 on the Linux subsystem of my own Windows 11 system in my pc to simulate a typhoon. When I use ONE processor, wrf.exe runs successfully but slowly. However, when I use 16 processors for fast running speed, wrf.exe runs several hours and output 4 hours wrf_out* data, then it...

    Differences between compile and compile_new with WRF v4.6?

    Hello all, I'm trying to compile WRF v4.6.1. I noticed that for version 4.6 and 4.6.1 there are configure_new and compile_new along with configure and compile. While for older versions, they only have configure and compile. I'm wondering what are the differences between configure and...

    Using RADM2's wrfchemi to follow the CMBZ MOSAIC chemistry mechanism will result in segmentation errors

    When I use the RADM2 wrfchemi, I choose the chem_opt=10 emiss_inpt_opt=101 and emiss_opt=4, the WRFv4.5.2 programme runs for some time and then ends the process, I check the rsl file and it just shows the segmentation error, here is my namelist.input, I hope you can give me some guidance! The...

    Using MOSAIC with Dust Emissions

    Hello, Is there a way to use MOSAIC with dust emissions in the WRF-Chem model? MOSAIC has 4 dust bins, while dust_opt uses 5 bins. I saw this post from a few years ago Problem running CBMZ-MOSAIC (4 bins) with AFWA dust scheme and was wondering if a solution was found. Thanks, Alexander

    any other process change chem array outside chem?

    Hello, I am wondering if there are any processes would change chem array (e.g. gas) outside of chem (chem_driver)? I have checked the dyn_em and PBL, shallow cumulus won`t change chem in my case. But i am not very familiar with the other processes beyond chem_driver such as "chem_adv_tim" and...

    WRF-Chem error at the start time: cma_ep.c:81, process_vm_readv

    Hi there, I'm running WRF-Chem with MOZART/MOSAIC option (chem_opt=201). The run crashes out at the start time with this error: I didn't find a similar error in the forum. Does anyone know what it is about? WPS and real.exe run with no issues. Also, when I use simpler chemistry options like...

    Data Format Issues Related to .bin Files

    Hi all. I'm using PRE-CHEM-SRC to generate file for WRF following the exercise2(NOAA - Global Systems Laboratory). Unfortunately the convert_emiss can't run well. So I had to write my own Python program to convert the .bin file generated by PRE-CHEM-SRC into the .nc format. However, when I...

    The wrfout file should be output hourly, but it is output every three days. And the hourly wrfout file can be output normally with chem module off.

    I used to use the meteorological model WRF. Recently, I added the chemical module and recompiled it. However, the wrfout file that should have been output hourly has been output every three days. When the chemical module is turned off, the hourly wrfout file can be output normally. I want to...
