segmentation fault

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...

Hey, I've been trying to run high-resolution WRF for the TC case (so there is also moving nests), and I've noticed that despite me cleaning and recompiling both WRF and WPS and regenerating new BC files for the model, it's still not running correctly. Essentially it has a SIGTERM error roughly...

Dear support team, I am running WRF (coupled to a snow model) over Antarctica. 1 domain (200x200), 27km resolution, 90sec time step. The model advances smoothly and writes the output files without problems, until it crashes with exit code 143, or 139 (segmentation fault), approx. 9 days into...

I am trying to run MPAS model forecast on the North America 3-km domain but my forecast stopped just a few time steps after hour 0, with the values of the global min, max w and global min, max u way too big. I am attaching the log file and namelist file here. Can somebody provide some clues on...

Hello, I was tried to running wrf.exe, the program crashed at the begninning with the error "d01 2023-07-27_12:00:00 in YSU PBL forrtl: severe (174): SIGSEGV, segmentation fault occurred" I had already increase the number of cores (up to 512!) and decrease the timestep length, as well set the...

Dear all, Thanks in advance for your kind help! I'm wanting to run European windstorm for Europe with major focus over France and Germany. Brief WRF set-up: D3 (9km) : D2 (3km) : D1 (1km) Time step = 30s: 10s: 10s/3 Initial and boundary conditions are taken from ERA5 (~25km and hourly) I...

I am trying to run a test case that downscales an individual ensemble member from the CESM2 Large Ensemble and when I run wrf.exe, I make it 15 time steps and then the model crashes for an unknown reason. I have not been able to find an answer for what this error could mean, so I am unsure if...

Hi all, While running wrf.exe I'm encountering an error forrtl: severe (174): SIGSEGV, segmentation fault occurred after simulating 2 days. Error is not coming immediately, it is coming after 2 days of simulation only when hitting the date 2017-11-29_21:52:30 always. I'm using 64 cores to run...

Hello everyone, I currently work on running WRF-Chem after Hybrid 3DVar-ETKF WRFDA, and encountered a persistent segmentation fault (wrfchem-run stopped at 'calls rrtmg_lw'). The Hybrid 3DVar-ETKF process contains the following steps: 1.wrf_3dvar_input_*.e001,wrf_3dvar_input_*.e002: Be...

Hello, I encountered a Segmentation fault error while running wrf.exe. When I tried to rerun using restart, the same error occurred. The error consistently appears in the file rsl.error.0049. I have attached my namelist file and all rsl files in the attachment. The command I used to run WRF is...

I've been testing WRF-Chem 4.6 on Linux x86_64 with dmpar INTEL (ifort/icc), and I've encountered a segmentation fault at the start of my simulation. To prevent this, I've had to add the following flags: -O0 -fno-inline -no-ip While this resolves the issue, I'm concerned that these flags could...

Hello! I'm writing this question after @kwerner prompted me to open a new thread for my issue (here). I'm new at this forum but have some experience with the model which was always supervised up until now. Currently, I am trying to run a simulation in order to later use WRFDA. All the...

Hi, I'm encountering a segmentation fault early in the integration of WRFv4.4 for an idealized simulation of a tropical cyclone. The simulation is configured with 2 nests and vortex tracking on the innermost nest. I compiled WRF with the debug flag and received the following error traceback...

Dear WRF Team, I hope this email finds you well. My name is Saikrishna, and I am currently engaged in the simulation of heavy rainfall events over India using the WRF model. My objective is to analyze both local-scale and large-scale features during these events. In my endeavor, I have...

Hello everyone, I'm running some simulations with WRF version 4.5.1 coupled with sf_urban_physics = 2 and bl_pbl_physics = 8 for three one-way nested domains for a month. Initially, I defined the eta levels with auto_levels_opt = 2, dzbot = 35, dzstretch_s = 1.3, and dzstretch_u = 1.1. This way...

Hello, I am trying to run WRF-Chem v4.5.2. When I use chem_opt=201, real.exe stops with a seg fault error. I have tried this with WRF-Chem v4.4.2 and I receive the exact same segmentation fault error. I have looked at the other posts and none of those solutions worked for me. I am still waiting...

Hello, I am trying to run WRF-Chem v4.3. When I use chem_opt=132, after real.exe it stopped after a few seconds. (attached namelist.input and rsl.error.0001) I really need help. Thank you!

Hello, I'm currently running WRF V4.5.2 built with Classic Intel compilers (dm+sm) on Princeton's research computing clusters. I'm using 0.25 GFS as input data, and when I run the model it always seg faults right before integration. The rsl.out/error files didn't show the fault, but I hope they...
