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

[rabbanidu93]

Hello there,
I have used 3 domains. While i visualize the parameter 'rainc' in the coarse/parent domain,
'rainc' region 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.

Yes, it's because you have cu_physics turned off on the nests, but it's also because you have feedback turned on. This causes the rainc on the parent to be overwritten by the '0' rainc from the nest. If you turn feedback off, then the domain1 will have rainc.
