    memory allocation error when running 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...

    WRF runs on convection permitting resolution crashes randomly in summer

    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...

    Issues to running real.exe and wrf.exe MacOS

    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...

    Please help!! WRF running real.exe automatically killed

    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...

    WRF simulation results are very slow at multicores processors

    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...

    Does increasing the number of processors speed up the "wrf" simulations while using MPI run ??

    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...
