As noted in TRNBuild (where you set the back side convection
coefficient), a value smaller than 0.001 is used to indicate direct
contact between a BOUNDARY wall and a temperature. A large value
(such as 999) is used with other wall categories (ADJACENT,
EXTERNAL, etc.) to indicate good thermal contact.
