Hi all,
I am ruuning WRF V3.7.1 with GFS FNL 0.25° for six summers during 2018-2021. Everything goes well except running year 2020. I came across the segmentation fault (signal 11) immediately after I execute wrf.exe. There is no error information in rsl.out/error files, which is weird. Even weireder, this didn't occur in running other fiver years with identical configurations.
I wonder how this happened, and need help from you all.
Thanks and best

We believe this is a data issue. if wrf.exe failed immediately, it often indicates the input data is wrong. Please compare your wrfinput of 2020 with that in other years. Hope this can give you some hints what is wrong. Due to limited human power, we no longer provide support for older version of WRF/WPS and data issue.
It's not immediately, but short time (about one or two minutes)after I run wrf.exe. Is it a data issue?
Wrfinput of 2020 is created by completing the real.exe successfuly. I don't know which variables to compare? The static variables are identical. Can I use wrfinput of other year when running WRF simulation of 2020?
