This is a benchmark test case for modeling the steady-state
temperature distribution in a thermal bridge in building
construction. The model consists of a 6 mm concrete slab subjected
to an outside temperature of 0 °C and heat loss due to
convection. The inside features a 4 cm layer of air enclosed within
a 1.5 mm metal frame, which is attached to the slab with an
insulating layer. The inside temperature is assumed a constant 20
°C. The model can both be considered to be planar, and also
symmetric at the ends so that only a 2D 0.5 m section needs to be
modeled. The heat flux and temperature at various points is compared
to given reference values .
