wrf bug

Hi everyone, I am encountering a persistent segmentation fault when attempting to run a coupled simulation with both the chemistry module and the Urban Canopy Model (UCM) enabled in WRF-Chem v4.5. Here are the details of my configuration and the testing I've done: 1. The Issue: The model...

I am a graduate student currently studying WRF. I would like to perform LES simulations, but I’ve run into some difficulties, so I’m here to ask for your help. I would like to know the specific steps involved in running an LES simulation. Do I simply need to adjust the parameters corresponding...

Dear all, I am trying to run WRF-Chem with WRF-4.1.1, but I got segmentation fault like rsl.error.0000. I found that when I change the ra_lw_physics and ra_sw_physics, WRF-Chem goes wrong. And sf_sfclay_physics should be 91 or it goes wrong when it was set to 1. The other scheme is OK, but once...

Hi all. I met a problem when I run WRF with grid nudging method. My current WRF namelist configuration is as follows. I used the data from ERA5 to drive the model, and I wanted to use nudging method to make the WRF results more close to the background meteorological data. Without nudging, the...

Dear friends: When I was running the wrf.exe program, it keeps running, but there were only two wrfout files. One was the valid file at the initial time of d01, and the other was an invalid file at the initial time of d02 (with a file size of 0). Thank you in advance for your help.

Hi, I'm adding microphysics source/sink terms to WRF output by modifying: Registry/Registry.EM_COMMON - Added variables (EPRDO, EPRDGO, etc.) phys/module_mp_morr_two_moment.F - Calculated variables in microphysics scheme phys/module_microphysics_driver.F - Passed variables through driver...

HOW CAN I SOLVE THIS PROBLEM? I USE CGLC_MODIS_LCZ_global DATA,PLEASE. THE FOLLOWING IS MY NAMELIST.INPUT.

Hi all — I’m seeing a reproducible WRF-Chem/KPP build stop that looks like an internal consistency issue in the CBM4 mechanism files During a WRF-Chem build (`WRF_CHEM=1`, `WRF_KPP=1`), the `chem/KPP/compile_wkc` step iterates over mechanisms and exits with: > `ERROR: variable name for third...

Hi all, I’m running WRF v4.7.1 with ERA5 forcing over a small Lambert domain in New South Wales (Australia). geogrid.exe, ungrib.exe, and metgrid.exe all complete successfully, but real.exe fails immediately with: ------ ERROR while reading namelist domains ------ Maybe here?: Maybe here...

Hi, I'm running WRF and repeatedly encounter model crashes (before walltime expires). The rsl.error.* files show the same error on either the initial run or a restart: forrtl: error (78): process killed (SIGTERM) Image PC Routine Line Source...

Dear Community, I am encountering a persistent issue while running WRF v4.1 for tropical cyclone vortex tracking simulations. The model runs successfully with the WSM6 or WDM6 microphysics schemes, but crashes immediately upon execution when I switch to the Thompson microphysics scheme...

I run em_tropical_cyclone, and when I used grep "cfl" rsl.error.*, I encountered this error. Could you please tell me how to improve or fix it? Here is my namelist.input and rsl.error.0027. Thank you very much!

Hi, friends I am a beginner learning WRF v4.2.2. While running real.exe, I encountered the following fatal error: However, I can confirm that I have edited and set up the namelist.input in the run directory, with parameters consistent with the previous namelist.wps settings. Initially, I...

Hello. I am using the CMIP data to run the WRF. It is successfully metgrid.exe， However, when I want to run the wrf,the real.exe will stop after 14 loop. I have try to change the time period, and get the same results. If I just loop 10,It will successfully real. I don't know what happend and try...

Hi all, I'm encountering a strange issue with auxiliary history output (auxhist7) during a long-term WRF simulation from 2013 to 2022. My Configuration: Regular output: Daily files auxhist7: Hourly output (for specific variables) auxhist7 settings: iofields_filename = "my-file_d01.txt"...

I am testing WRFV4.1 with sf_ocean_physics=2 and enabling preset moving nest. The program crashes without any errors in rsl.error files. When I disable 3d-ocean and set sf_ocean_physics=0, the model runs fine, indicating that the issue may be related to 3dPWP. Additionally, when I deactivate the...

Hi everyone, I have been trying to run real case scenarios (12 km -- 3 km -- 1km) over the city of Bhubaneshwar following some idealised simulations I ran over this city. I try to deviate as little as possible to my idealised simulations configuration but I am facing issues. The model runs only...
