Hi there,

When I tried to convert cdump to grib1 format using con2grib.exe I got this error after some successful steps:
...

Segmentation fault

The simulation uses WRF output produced ARL file. Confirmed the error is not related to resolution or domain size.

Another thing is when I use ERA5 produced ARL to run instead while keeping the rest setup identical, the cdump produced can be converted by con2grib.exe without a problem.

Has anyone come across the same?
