    WRF freezes, keeps running but it doesn't write the output

    I tried to do that, but it didn't work. I was using SMS-3DTKE, so I changed it for the Shin-Hong scheme and worked, now it's running more stable.

    WRF freezes, keeps running but it doesn't write the output

    Yes, is over the Andes. My problem is not getting CFL errors, I have to deal with that in this area, but the problem was I wasn't getting an error message and the process was still running. I compiled WRF with intel compiler + OpenMPI, and now I get an error message. So, I think I might be...

    WRF freezes, keeps running but it doesn't write the output

    I've made some tests. And the problem seems to be the intel compiler or intel MPI. At the same time it freezes, I get CFL error using gcc and OpenMPI

    wrf.exe fails a few minutes after starting

    In my case, I use different parameters. But the best options to avoid the cfl errors, I think would be changing to mp_physics=3 and some brute force way would be increasing the epssm value.

    wrf.exe fails a few minutes after starting

    First try turning on w_damping and if it doesn't work, change the time_step.

    [SOLVED]wrf (intel compiler) crash

    Try setting the HDF5 library paths like this before configure: and then check that HDF5 is correctly linked in configure.wrf I think these are all the references in the file:

    [SOLVED]wrf (intel compiler) crash

    I think that's a netcdf problem and not the intel compiler. Try compiling with classic data model from netCDF-3, without compression. If you want to use compression, build netcdf with hdf5 without activating parallel I/O.

    WRF freezes, keeps running but it doesn't write the output

    It has happened in two different computers, using WRF 4.3.3 and 4.4. Now I will start running a new model, if it freezes again I'll upload the namelist.input. The rsl files just stop writing, doesn't show any error. I thought it could be some memory or disk errors, but seems that everything...

    WRF freezes, keeps running but it doesn't write the output

    I've been having random errors where WRF process keeps running, but it doesn't write the output data (wrfout, wrfrst, rsl). The only way to fix it is to change the timestep or change the microphysics parametrization (ie. from 6 to 3). This happens randomly, different servers, different...

    Yes, it's also set auto_levels_opt = 2

    Modelling over complex terrain at high altitude

    Thanks! that's what I was thinking about the SMS-3DTKE scheme. I'll do some tests to check the different options.

    Setting first layer thickness

    Those eta levels are the calculated by wrf, I didn't specify it in the input file. I have it configured like this: e_vert = 44, 44, 44, 44, p_top_requested = 5000, num_metgrid_levels = 38, num_metgrid_soil_levels = 4, dx...

    Modelling over complex terrain at high altitude

    I want to set up a model over a complex terrain at high altitude (between 3000m and 5000m). The main problem here is that sometimes the surface wind field is forced by the model to make a wind direction daily cycle, instead of one steady direction (mainly from the north). So, I most of the time...

    Setting first layer thickness

    I tried to change de default 50m for the first layer to 20 m by using dzbot= 20 and keeping everything else default. When I check the namelist.output seems ok, but when I check the vertical levels, are the same than the default setting. Is there anything else I should set? I'm using WRF 4.4...

    About LANDUSE.TBL use of summer/Winter data

    The LANDUSE.TBL file has summer and winter parameters, how does WRF knows when use summer or winter? the months are set by default or can be modified in other file? and if it's used in the southern hemisphere, is it ok to use the same file or has to be adapted?

    Error in real.exe P array = NaN

    Well I realized that I was doing the nest down wrong. So, could it be that the resolution I was using for the first domain was too high (3km) so it had some problem for creating the wrfbdy_d01?

    Error in real.exe P array = NaN

    What I'm trying to do is to run ndown. So first I run the first and 2nd domain and now I want to run a third domain. So now I run WPS for the 2nd and 3rd domain (now domain 1 and 2) without any problem. The only problem happens when I run real.exe, which was ok when I did the first run. I...

    Error in real.exe P array = NaN

    I didn't have any error message, just the segmentation fault forrtl: severe (174): SIGSEGV, segmentation fault occurred
