real.exe error invalid parent id for domain 2

Hi guys.

Whenever I run wrf.exe it gets this error:

taskid: 0 hostname: n0020
module_io_quilt_old.F 2931 T
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE: <stdin> LINE: 5578
invalid parent id for domain 2

Thanks！

Hi,
Typically this error doesn't mean what it says, and I'm not sure why that is. It usually has nothing to do with the parent ID. We usually find that there is some other namelist.input error. I didn't look at every single variable, but I do see that this one (time_step) that has an incorrect setting:

time_step                      = 7.5,

The setting for that variable must be an integer (whole number). If you want to use fractional time steps, you can use these two variables to do so:

time_step_fract_num            = 0,
time_step_fract_den            = 1,

Thanks!
I have changed the time_step from 7.5 to 60,and I can run WRF sucessfully.
