running wrf

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...

Hello, I have encountered the following error while running wrf.exe: For domain 1 , the domain size is too small for this many processors, or the decomposition aspect ratio is poor. Minimum decomposed computational patch size, either x-dir or y-dir, is 10 grid cells. e_we = 93...

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...

Hello Sir/Ma'am, We wanted to conduct a study to evaluate the impact of urban natural vegetation on air temperature. In order to do that, We have used the default geo_static_data (modis) for our calculation. So we have done two case with different SHDFRAC values (based on my understanding...

Hi, I am using WRF-LES to conduct simulation experiments at a 30-meter resolution. The compilation was successful since I can run both ideal.exe and wrf.exe with the default namelist.input. However, when I start using double nesting, wrf.exe throws an error, and I have uploaded the error log...

Dear all, I am running wrf.exe (version 4.5.2) in an HPC. As I want to include some important parameters in the WRF output file, I created a text file ('my_iofields_list.txt'), one for each domain, defined in the namelist.input file, located in the 'time_control' namelist record by following the...

Hello, I had a problem running wrf.exe. I use nohup mpirun -np 64 ./wrf.exe & to run wrf. It stopped after running for some time. The error occurred in file rsl.error.0015: [localhost.localdomain:2811056] Read -1, expected 151200, errno = 3 and I want to ask how can we solve this problem...

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...

Hello, I have already successfully executed real. In running wrf I receive the following error: open_hist_w : error opening /glade/derecho/scratch/$USER/spillover_200612/wrfout_d03_2006-12-13_00:00:00 for writing. That particular folder is empty. I have exhausted my troubleshooting checklist...

I am a graduate student and I need to use the WRF model for my thesis entitled "Investigation of Wave Energy Potential on the Black Sea Coast". I will not use it for professional purposes, and I need to perform a simulation in the simplest way possible. I cannot provide more details since I am...

Hello, I am trying to run WRFv 4.5.2 on Derecho (using the pre-compiled version on Derecho), and have been running into issues during my second restart run. The model runs quickly for the initial run, and for the first restart run. However, on the second restart run, things slow down a lot, and...

I'm conducting one domain experiment and two domain experiments with WRF version 4.4.2. I am using openmpi 4.1.4 version and aarch64, a 64-bit processor based on the ARMv8 architecture. It was confirmed that the experiment set with two domains was completed normally, and the experiment with one...

Hello everyone, I would like to request a little help with this issue. I am working with WRF v4.4 and v 4.2 in both cases I try to launch a simulation with output data writing every 10 minutes. My understanding is that it should be simple by defining history_interval = 10. But for some reason...

Hello all, I am running WRF v 4.1.2 on virtual machine using GNU Fortran (Ubuntu 9.4.0-1ubuntu1~20.04.2) 9.4.0. The simulation is for em_real module running for 24hrs from 2009-05-06_06 to 2009-05-07_06. I am able to run real.exe but not wrf.exe. The simulation stops running at the 10 minute...

Dear all, Hi, I'm trying to run WRFv4.0.3 with fnl grib2 data. But after a few seconds running wrf.exe, it suddenly stops with no error. I tried it in serial, also with 16 mpi but it always stos at the same point. With mpirun, this stops with this message. starting wrf task 0 of 1 (it repeats...

Hello everyone, First, sorry for my English. I hope you understand. See, I have a problem of Segmentation Error. I already saw many post about that and I concluded that it was because of inestability of the model, so I change my timestep of 60 to 30 and it worked. However, I seem the time of...

Hello, I am working my way through the online tutorial and I keep running into a segmentation fault for the 2-way, 1 input file nested domain run. Unfortunately these faults are not very useful when trying to debug so I was wondering if anybody else has run into a similar issue? What was your...

Hi All, While running WRF I'm getting p_top mismatch error. Timing for processing wrfinput file (stream 0) for domain 1: 32.93626 elapsed seconds Max map factor in domain 1 = 0.00. Scale the dt in the model accordingly. D01: Time step = 120.000000...

Hi all, I am new to installing the WRF model. I have a virtual machine with Linux RHEL 6.4, where I have previously installed WRF version 4.0.1, and I run the model daily for 48-hour forecasts. I have tried to install the WRFV4.4.2, but I get the following warning before compiling...

Hello. I'm trying to run the latest version of the WRF model by implementing the hybrid 100-m global land cover coupled with the BEP urban parameterization. I have 3 nested domains with 12 km, 4km, and 1km horizontal resolution, respectively. Unfortunately, during the simulation of the first...
