    MPAS-A issues with parallelization: Segmentation fault

    Dear, I'm having some (hopefully standard) issues running MPAS-A. I'm running a regional circular domain of 1500 km diameter on a 3km resolution. Using ERA5 as initial and boundary conditions, and OSTIA for sea surface temperature, ./init_atmosphere_model runs fine and the and lbc*.nc...

    Modify static data in WRF but segmentation fault

    Hello ! I want to replace the static data of LAI, ALBEDO, and LU_INDEX in WRF. I chose to directly replace the data. After the replacement is successful, both metgrid.exe and real.exe can run successfully, and the resulting data is fine. However, in the final step of running...

    GEOGRID.exe Segmentation error

    Anyone please give solution. I am trying to run geogrid for nested domains and recieved this error. Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x7f1bfd487d21 in ??? #1 0x7f1bfd486ef5 in ??? #2 0x7f1bfd16908f in ??? #3...

    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...

    Program interrupt in RRTMG LW CLWRF interpolated GHG with Segmentation fault (signal 11)

    The strange thing is that I run my program at other times without problems, but in July 2019, he always keeps interrupting without detailed error reporting information, and the interrupt points are usually RRTMG LW CLWRF interpolated GHG values year: 2019 Julian day: 182.270142 I've...

    Segmentaition fault when running wrf.exe

    Hello all, I'm running WRFV4.5 with sf_urban_physics=1 (i.e., SLUCM), unfortunately, the model stopped after integrating several hours. The error information which I got is as follows: [ib0414:86410:0:86410] Caught signal 11 (Segmentation fault: address not mapped to object at address...

    segmentation error when running 3km resolution but success in 10-km

    Hi ,everyone, I'm having a little trouble running init_atmosphere I am running MPAS-A 7.3 using single precision with era5 data to generate INIT file , but faile because segmentation fault。Like this: So, we print variable A in mpas_atm_advection.F, and found NAN and INFINITY, like this: Our...

    Transient seg faults

    Newbie to WRF. Version 4.5. Successful compilation under WSL2 Ubuntu 22.04 (after a few days of permutations, of course). Running 9 km dx=dy. 0.25 GFS initialization. 8 processors. 24-hour run. (namelist.input attached. The rsl files don't show much out of the ordinary, except for what...

    Polar filter segmentation fault

    Hi, Has anyone used the polar filter? I was running WRF v3.8.1 (LES mode) and was just testing the FFT routine by enabling the call of the subroutine pxft in solve_em.F (I commented out the "IF (config_flags%polar) THEN" and "ENF IF" statement). Then when running wrf.exe, I got segmentation...

    WRF Restart Runs Fail When Mosaic Land Use Tiling Is On

    Hello, I am attempting to run nested (9km x 3km x 1km) urban simulations with the use of the mosaic landuse categories option. The simulation is stable and the output is realistic when I initialize and integrate the model forward in time. However, whenever my compute limit is reached and I...

    Segmentation fault after N time steps in real.exe with ERA5 boundary conditions

    Hi all, I'm attempting to run a three-month simulation with WRF using ERA5 boundary conditions. I have successfully generated the metgrid files and real.exe runs fine for small time subsets. When I try to run real.exe for the full simulation time it segfaults, always during loop number 626. The...

    (RESOLVED) forrtl: severe (174): SIGSEGV, segmentation fault occurred --> namelist typo

    Hello, I already read multiple posts on this forum quoting this error but none of the provided issues to check or solution to try seemed to work (e.g. : no CFL error). I'm using inputs from ndown.exe (originating from wrfout* by WRF 3.6.1) into a 2-domains (121x121) nested run by WRF 4.2.1...

    Segmentation fault running WRF with nested domain

    I'm trying to run a real data WRF simulation (initialised with NCEP data) with one nest on an HPC cluster. All the WPS setup programs (metgrid, geogrid, and ungrib) completed successfully, as did real.exe. When I run wrf.exe it produces the first wrfout file for each domain and then crashes...

    Segmentation fault when using nested domains

    Hello everyone, I'm trying to run WRF-CHEM with all the chemistry options turned off, just to test that it works as expected. The idea is to add biogenic emissions later when we check that everything is ok. The first test simulation without nesting worked fine. However, WRF-CHEM raises a...

    Segmentation fault in WRFDA when assimilating AHI data

    When I assimilate the AHI data on WRFDAV4.4, I get a memory error, but when I assimilate it at another time, it works fine, and I have re-downloaded the data several times with the same problem. According to the output of the rsl.out file, the program ended at the time of the VARBC. I would...

    Hi, I am running the following simulation (see namelist attached), which works fine for some selected days but not for others. For the one attached here it crashes after some time without any clear error message.I tried reducing the timestep from 10 to 1 and also added ulimit -s unlimited, but...
