rainc is absent in coarse domain only in the nested domain region

Hello there,
I have used 3 domains. While i visualize the parameter 'rainc' in the coarse/parent domain,
'rainc' is absent in coarse domain only in the nested domain region.
Is this because of my cumulus scheme // cu_physics = 1, 0, 0, // ???
See the picture attached herewith. I've also attached my namelist.input

Thanks in advance.

I am sorry to answer so late. Somehow this post was skipped.
This is a common feature when you run nesting cases with feedback on. If cumulus scheme is turned off in the child domain, then rains will always be zero and it feeds back to the parent domain, making rainc to be zero there.
