segmentation fault

Hello I'm trying to get some output variables of geogrid process in high-resolution to South America, but the geogrid is raising Segmentation Fault error. I'm attaching here the namelist.wps file that I've made with WRF Domain Wizard. Is there any limitation in the number of cells in geogrid...

I am attempting to run three separate WRF runs, all of which are unsuccessful and throw the same errors: "rank XXXX died from signal 11" and "rank XXXX died from signal 15." A quick search reveals these are segmentation faults, with signal 11 indicating an MPI segmentation fault. Screenshots of...

I am running WRF_Solar v4.5 and the model crashes immediately at the start of the job. I’ve attached the rsl.error.0000 file and my namelist.input. please help me to identify and fix the issue.

Hi, I am running a simulation over 3 domains (9-,3-,1-km) to examine the role of cloud radiative feedback on coastal convection. Following other threads, I have included the following: 1) icloud = 0 2) cu_rad_feedback = .false.,.false.,.false. 3) shallowcu_forced_ra = .false.,.false.,.false...

Hello all, I'm using WRF-Solar shcu_physics=5 (Deng) to simulate the shortwave radiation conditions over the whole China, but got a "segmentation fault" error, it seems like this error is related to the Deng shallow cumulus scheme. I'm not sure if I might have missed some parameter settings...

Hi I've just built WRF 4.7.1 and WPS 4.6.0 using intel (oneapi) and OpenMPI on our new HPC, but my test run fails when I get to running real.exe with: `forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed Write` if I put debug level up (I note that...

real.exe runs successfully, but when I try to run wrf,exe gets the following error. Please help me to resolve this issue INITIALIZE THREE Noah LSM RELATED TABLES Input data is acceptable to use: WRF NUMBER OF TILES FROM OMP_GET_MAX_THREADS = 1 Tile Strategy is not specified. Assuming 1D-Y...

Hi all I'm trying to get to the bottom of some weird issues when running WRF. - I was initially trying to run it on a large memory 64-core VM. WRF fails to complete both in serial and dmpar modes - I ran it on a cluster I have access to. With the same data / namelist files, WRF completed when...

Hi, I am currently using ERA5 data to get parameters such as QCLOUD. The previous steps (geogrid, ungrib, metgrid, real programs) run successfully. However, when I run wrf.exe, following error occurred. I have attached my namelist.input, rsl.error.0000 and rsl.out.0000 for review. Thank you...

Hi, I have previously successfully run my WRF model with the current settings I have, only with a smaller set of nested grids. In expanding the grids to cover a larger area, I am now running into new errors. I have adhered to "Choosing an Appropriate Number of Processors" as described in FAQ...

I am using future scenario data from MPI-ESM1-2-HR for downscaling, but I encountered a 'Segmentation Fault: Invalid Memory Reference' error while running real.exe. Below are my rsl.error, rsl.out, and namelist.input files. Could you please help me take a look at this issue? I’d really...

I'm running WRF452 on the Linux system in my own pc to simulate a typhoon. Wrf.exe runs successfully when e_we=27, e_sn= 27. However, when I replaced them with e_we=270, e_sn= 270, wrf.exe runs several hours and output 10 hours wrf_out* data, then it collapses with the following error...

Hi, I have completed a 4-nested simulation with resolutions of 12150-4050-1350-450m using WRF 4.0, and used ndown to make the driving file for 150m. However, when continuing the 2-nested simulation with 150m and 50m resolutions, I encountered "Segmentation fault" in module_sf_sfclay. This error...

Hello all, Greetings! I'm trying a LES simulation in the em_real folder. I did WRFDA assimilation for the initial moments. I am running the simulation on the server and using 120 processes. Due to server math, runtime, and cost issues, I am using a maximum of 120 processes and time_step cannot...

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...

Hi everyone, I have set up the WRF model 4.5.1 for a long-term historical and projection run, spanning 20 years, with forcing data derived from NoeESM2 GCM. The model is configured to run with SLUCM coupled to the Boulac PBL schemes. The outer domain covers Europe at a 12 km grid resolution...

Dear WRF Users, 1. When I run ./real.exe, an error occurs. From the error log, it seems that there is no problem in the first two time steps of simulation, but it crashes in the third time step. 2. i Use Copernicus ERA5 Data with WRF !!!!!!!!!!!!!!!!!!!!!!!!!!!!! Domain 1: Current date being...

Good morning, I am a beginner and trying to learn how to run the WRF LES model to simulate the flow of tracer particles named 'plume' at a certain wind speed with 2 domains. When I set the simulation time to less than 1 hour, it runs fine, but when I set it to 5 hours, the program always stops...

Dear all, I'm Mimi. Thank you so much for always helping me..!! Now I'm currently working with WRF FIRE and aim to apply observation nudging with AWS data. I'm still getting familiar with converting data into little_r format, so I’m practicing with NCAR observation data in little_r as a first...
