modelOpaqueSurface
Model for an opaque surface
Extends from Buildings.HeatTransfer.Radiosity.BaseClasses.RadiosityOneSurface (Model for the radiosity balance of a device with one surface), Buildings.HeatTransfer.Radiosity.BaseClasses.ParametersOneSurface (Parameters that are used to model one surface).

Revisions
-
October 24, 2016, by Michael Wetter:
Removed declaration ofT03as it is already declared in the base class. -
May 30, 2014, by Michael Wetter:
Removed undesirable annotationEvaluate=true. -
June 27, 2013, by Michael Wetter:
Changed model because the outflowing radiosity has been changed to be a non-negative quantity. See track issue #158. -
February 10, 2012, by Wangda Zuo:
Fixed a bug for temperature linearization. -
