confused by "periodic Non-Conformal Grids"
 
Hi,everyone!

I am reading the "fluent 6.3 user's guide" these days. But I am confused by two of the Requirements and Limitations of Non-Conformal Grids:

1. For 3D cases, if the interface is periodic, only one pair of periodic boundaries can neighbor the interface.

2. Periodic interfaces require conformal periodics adjacent to it. For example, when you calculate just one channel and blade of a fan, or turbine, etc., you must have conformal periodics on either side of the interface threads. This will not work with nonconformal periodics.

Can anyone help me ?

Thanks in advance.

Regars,
