I am running WRF 4.2.1 on my Laptop. While running wrf.exe I am getting error

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Segmentation fault (core dumped)


this error is generated after 5-10 mints of running wrf.exe (a little later )
I have compiled WPS and WRF both serially. I dont understand this error and where to fix. there have no error file generated. below I have attached namelist of WPS and WRF

Due to the above problem, I have again compiled wrf in (dm+sm) mode and WPS is serial model.

In that case when I run wrf.exe, I got this error

Kindly help me out from this problem. Here below I am attaching namelist of WPS and WRF.

Your namelist.input looks fine. Segmentation fault often indicates a memory issue or something wrong in physics.
Can you look at your log file to check whether there is any error message? You may also save the wrfout every time step and look at each file to see whether there is any weird pattern or unreasonable values of the output variables. This is to figure out whether anything is wrong in physics.
