wrf.exe

I am trying to run WRF on a domain with a parent and one nested domain using the real case with ERA5 data as the input for boundary data. I have worked through every step with WPS and ran real.exe without errors. When I try to run wrf.exe, I am receiving the following error: MPI_ABORT was...

Dear support team, Thank you for the incredible support here. It has become a great resource for help even without opening new threads. My team has some experience with WRF. In our current application, we want to run simulations with large domains, but now we ran into segmentation faults. The...

Hello I am getting this error error opening wrfinput_d01 for reading ierr= -1021, while running wrf.exe. Also, I can see that wrfinput_d01 and wrfbdy_d01 are not created. I am attaching my namelist.wps and namelist.input files.

I am getting below error while running wrf.exe over Himalayan region. (Please find attached namelist.input file which I am using.) Kindly suggest the solution on this. Thanks. ERROR: Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0...

Hello. I'm trying to run WRF and get this error when executing the "wrf.exe" file: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 2033 QG, QG(NK).LT.0 ------------------------------------------- application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0...

hi, everyone I encountered a problem when running wrfchem. wrfchem works properly when chem_opt=6, but an error occurs when chem_opt=7!

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...

I am using WRF to simulate a real case.I have given the start time as 2024/12/01_00:00:00.The simulation is for 23 hours.While running ./wrf.exe, my simulation terminates with the error as shown Input data is acceptable to use: wrfinput_d01 CURRENT DATE = 2024-12-01_00:00:00...

Hi everyone, After a lot of try and errors I could finally compile WRF and WPS without any major issue for MacOS with M3 pro chip. I'm trying to run the Matthew hurricane example, but when I run real.exe it's fails, even using the examples that the tutorial gives you. Also I recompiled the...

Hello, I am running WRF on derecho for 3 domains. I set the wall clock time to 12 hrs but my job got ended in 4th hour. I have attached the namelist.input , job script and rsl.error and rsl.out files below.

Hi, I run wrf.exe with 16 processors I get the following error: =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = EXIT CODE: 139 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP...

Hello all, I am attempting to run WRFv4.3.1 with ERA5 initial conditions. I am able to get through WPS with no issues and real.exe "completes without issue". However, upon running runwrf.csh, I am only able to get through the first output time for each domain, followed by "forrtl: error (78)...

Dear Members, I hope everyone is doing great. I am running a real case using WRF 4.3.3. This is the only version that I can compile WRF successfully. IN configration, I chose serial (32) and Basics (1). I have encountered an issue to run a nested case with 3 domains in total. However, when...

Hi, I am using a Linux cluster with GNU compilers to run WRF simulations using mpirun. Currently, I am using 9 nodes with a total of 36 cores, and the CPU usage appears efficient. I have four domains, each with a grid size of 250 × 150. However, I am only getting 11 seconds of simulation...

大家好： 我运行的是 WRF4.0，使用 mpirun 运行 wrf.exe 时出现一些错误，详细错误附在下面。您能告诉我如何修复这个错误吗？而 rsl.error 文件只有 rsl.error.0000。 感谢您的想法。

Hello, I've started using WRF over the last year. From NCAR tutorials and WRF user guide, I came to know that using more than one processor would improve my model performance and also optimize the total model run time while using mpirun. So, accordingly, I've followed the guide present on this...

I get the following error when I try to run wrf with updated IC and BC after DA. d01 2023-07-07_00:21:50 21 points exceeded v_cfl = 2 in domain d01 at time 2023-07-07_00:21:50 hours d01 2023-07-07_00:21:50 Max W: 43 563 18 W: -61.60 w-cfl: 4.20 dETA: 0.02 Could...

Hello, so ive run the obsgrid.exe ofr the first time and get the message on the obsgrid.out : Time Loop Processing, date = 2024-09-07_06:00:00 Using ./OBS_DOMAINd01:2024-09-07_06 as obs input file Number of observations successfully ingested: 1. Number of empty observations discarded: 0...

I have tried the following methods without success: 1. grep -rn "cfl" rsl.* 2. w_damping = 1 3. ulimit -s unlimited The meteorological data should be fine, as I have successfully run a case previously using this dataset. This time, I increased the resolution and added sst_update = 1, but it...

Hellow I want to figure out how to truly specify non moving domains in vortex following? I am currently setting it up as follows: time_to_move = 99999999,9999999,0,0, But when I want to make some interesting attempts, it doesn't work properly:
