    WRF Running Help For New User

    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...

    I have a problem writing output data every 10 minutes

    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...

    wrf.exe always stops at the same point

    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...

    Segmentation Error or decrease the runtime

    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...

    Tutorial nested domain runs - segmentation fault

    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...

    WRF.exe segmentation fault

    Hi, I am trying to run wrf.exe (version 4.5) for a nested domain, but after a couple of minutes (and after writing the output of the very first time) the model stops with "segmentation fault". I do not see any CFL errors in the rsl files (or any error at all) even when I configured wrf with -d...
