Dear WRF Users,

1. When I run ./real.exe, an error occurs. From the error log, it seems that there is no problem in the first two time steps of simulation, but it crashes in the third time step.
2. i Use Copernicus ERA5 Data with WRF

Hi,
Although real.exe typically doesn't need many processors to run, your domains are rather large. Can you see what happens if you use more processors? Try something like 36 or 64. If it still fails, please package all the rsl* files into a single *.tar file and attach that. Thanks!
