Class 3 Error
For conjugate heat transfer problems, it is possible to get incorrect temperatures, for example outside the expected bounds, when 1-1 domain interfaces are used. This can occur at fluid-solid interfaces when:
(1) there is a large conductivity ratio
(2) radiation is being modelled
(3) the flow is modelled as laminar,
and for solid-solid interfaces with large conductivity ratios.
There is a bug when using 1:1 domai
Use a GGI interface instead, except for some multiphase cases.
