Revisions
-
March 13, 2015, by Michael Wetter:
Changed model to avoid a translation error in OpenModelica. -
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. -

Declared the parameter record to be a parameter, as declaring its elements to be parameters does not imply that the whole record has the variability of a parameter.
