[Wrf-users] Fwd: two way nest run crashes without errors

[Xin Xi]

Hi I am running wrf 3.6 with two way nesting. After the spinning up on
outer domain, the program stopped without any warning or errors. in other
words, the program simply stopped at the beginning of the nest domain start
time. I wonder whether this is an issue of parent_grid_ratio (=15), time
step or the vertical lvls. Please help. Thanks.

 Here is excerpt of namelist.input:
