Class 3 Error
The CFX Solver does not support mixing of radiation models across a solid-fluid interface with a "conservative interface flux" condition for thermal radiation. However, for example, if a case is set up with the discrete transfer model in the fluid and Monte Carlo in the solid, then neither CFX-Pre nor the CFX Solver gives any warning, but the Solver continues in an incorrect manner using the discrete transfer model everywhere, even in the solid where it should be disallowed.
This is due to poor checking of model
No workaround is currently available.
