Thermal SurfaceThermal surface properties can be assigned to surfaces of thermal conductive materials. A thermal surface property definition describes the radiation and convection losses from a surface.
Name
Declare the name for the thermal surface. Each surface must have a unique name.
Radiation properties
Emissivity:
The Emissivity 
is a dimensionless constant within the interval
0 and 1, which describes the radiation from a previously defined surface:
,
where 
stands for the radiated power, 
for the surfaces temperature, 
for the background temperature, 
for the Stefan-Boltzmann constant and 
for the area of the selected surfaces. An
emissivity value = 0
means that the surface does not lose thermal power by radiation; a value
of 1 means that the surface emits thermal power as good as the so-called
”black radiator”.
Convection properties
Heat transfer coefficient:
The Heat transfer
coefficient 
describes convection processes at the surfaces of conductive
materials:
,
where 
denotes the power, the surfaces temperature, the background temperature and
the area for the selected surfaces.
