KNOWN ISSUE: Solid-solid interfaces and 1-1 connections (Class 3 Error if it were not mentioned in errata)
When using 1:1 periodicity within a solid zone in a simulation which also involves a multiphase fluid domain, the user may obtain incorrect results or the CFX-Solver may crash.
There is a potential memory overwrite in the CFX-Solver for this combination of features.
Use GGI periodicity.
