    Segmentation fault while writing restart files

    Hello, me and my colleague ran into a segmentation fault right when WRF was about to write the first restart file more specificaly during writing for a nested domain. This problem happened exactly at the same time with both of our computer despite the fact that we were using different time...

    Segmentation Faults just prior to integration

    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...

    WRF openMPI error on Slurm

    I am running the WRF model in a slurm environment using openMPI. A slurm script called "wrf.slurm" was used to perform work on the compute node, and the following error message was written to rsl.error.0018. When I ran the same script two days ago, it ran normally, but after the error occurred...

    Ground heat flux of Noah-MP LSM

    In WRF, when using Noah-MP as the land surface model with sf_urban_physics enabled, I observe anomalous results for ground heat flux (G Flux). The flux in Noah-MP is calculated with the downward direction considered positive. Conversely, in UCM (Single-layer), G Flux is positive upward, causing...

    WRF:NUM_METGRID_SOIL_LEVELS = 0 (from met_em files).

    hi,all when i run real.exe, i got an error like: After some checking, I realized that it was caused by the inconsistency with namelist.input due to NUM_METGRID_SOIL_LEVELS = 0 in my met file. But this met file is generated by the FILE:xxx file I wrote via py, after metgrid.exe, and I really...

    WRF V3.8 input conversion error

    Hello, I recently encountered a strange problem. I am unable to progress my WRF model after performing data assimilation, which generates an analysis. The error message is as follows: forrtl: severe (64): input conversion error, unit -5, file Internal Formatted Read Image PC...

    Segmentation fault while running wrf.exe at 1km resolution

    Hi, I am using the WRF v4.0 model for simulations over the mountainous region of India. Model IC/BC is being used from ERA5 datasets. Simulation has three domains, i.e., D1 = 20 km, D2 = 4 km, and D3 = 1 km resolution. WPS and WRF-real completed without any error messages while running wrf.exe...

    ECMWF error in running real.exe

    Hello everyone, I'm currently trying to run WRF using the ERMWF data. I've already succeeded in running ungrib and metgrid (after downloading surface and level data separately and running ungrib twice). However, when I run real.exe, an error occurred. I've attached my namelist.wps and...

    Vertical loop index in subroutine "advect_w" when the polar flag is on

    Hi. I'd like to ask about the vertical loop index (for tile, kts, and ktf) in WRF(v3.8.1). In the subroutine advect_w located in dyn/module_advect_em.F, I found that the vertical loop index is kts:ktf as shown below. ``` IF ( config_flags%polar .AND. (j == jds+1) ) THEN DO...

    [SOLVED] Segfault for WRF V4.5 with the new hybrid 100-m MODIS-LCZ dataset using SLUCM urban physics

    Hi, I came across segfault for WRF 4.5 using the new modis-lcz dataset under SLUCM urban physics. The segfault always happen at 1 of the 72 cores in Cheyenne. From the error log it seems that the segfault happens during avgflx at solve_em.F. I cannot pinpoint how it happens without any...

    Simulation results change when I only made modification to Registry/Registry.EM_COMMON

    Hello, I met this problem here with WRF-v4.4.1. After I made some modifications to Registry/Registry.EM_COMMON (without changing any part of the other codes) and recompile, the simulation results changes. The modification includes two new variables in "NSSL WRF diagnostics" part, and add an...
