KNOWN ISSUE: Diffusion discretization at non-overlap GGI boundaries may use volume fraction instead of contact area fraction (Class 3 Error)

The diffusion term discretization at non-overlap GGI boundary conditions may use volume fraction where it should use contact area fraction. This will not normally lead to a large error, but the error may be significant for cases where molecular thermal conductivity is large (e.g. liquid metals).

This is due to the use of uninitialised local variables in the CFX-Solver.

No workaround is currently available.

ANSYS CFX Release 12.1. A custom executable for ANSYS CFX Release 12.0 is available on request.
