Finding adjacent cells by UDFs
 

Hello,

I am trying to reach cells inside the sphere to make calculations at each cell. But I want to solve such equations that, I need to reach the cell just next the cell which are standing radially alligned. Or, they are standing through the center of the sphere. In the connectivity variables part of the UDF manual, there are some functions available but I want to see an implementation. Is anybody has an experience on that?
