ZERO VALUES IN RAINC AND RAINNC

[utkarsh-7]

Hi,
I was trying to run the WRF model to see the precipitation data during the storm, but every time in the WRF output I get zero values in the RAINC and RAINNC variables. So is there some particular namelist configuration or some other output variable in the WRF output that gives the precipitation data?

Attached both the namelist files for reference -

There are a few issues here:

(1) In your namelist.input, you have the options:
mp_physics = 0, 0, 0
cu_physics = 0, 0, 0

This means that you turn off microphysics and cumulus , which is physically unreasonable. Please select correct options, for example,
mp_physics = 8, 8, 8
cu_physics = 16, 16, 0

(2) please set dx and dy for all domains, i.e.,
dx = 12000.0, 6000, 2000,
dy = 12000.0, 6000, 2000
