[Wrf-users] Fail to run WRFV3.9 with specified eta_level

[田越]

Dear all,


I`m currently running WRF Version 3.9 with 35 specified eta_levels, for the default vertical levels are not dense enough to study the boundary layer phenomenon. However, the calcution always stopped at just few seconds. 


I have checked rsl.out.* and rsl.error.* files, and there`s no obvious error message.


I wonder if it is related to the numerically unstable issues, so I have tried different timestep such as 81, 54, 27, 18 ad 6s, but still got CFL prints in the rsl.* files.


Can anyone figure out the reason? Or how can I get more detailed error message? Looking forward to your suggestion.


Here`s my namelist.input :
