[Wrf-users] wrf.exe stops without any error

[Agnes Mika]

Hallo Nuria,

 Check if any of your rsl files contain a CFL error message. You can
 do this quickly by typing, e.g.:

    grep cfl rsl*

 It often happens that there are no CFL errors shown in the
 rsl.error.0000 file but they are present in some of the other files.

 If the grep returns results then you need to make your timestep
 smaller.

Hope this helps,
Agnes
