Folks,
I need help on how to use IRTMaterial, the infrared material. I
basically have a naturally ventilated space with an opening - not a
window, just an opening where the airflows. The best to model this type
of surface is to define the infrared material, where (a) there is no
surface convection (at least can be minimised) and (b) the surface will
let the solar radiation into the zone.
