Updated package Rooms.Constructions and the model for the exterior boundary condition to make it compatible with the new convection model. Corrected a wrong implementation of the frame convection model in the example models ExteriorWallTwoWindows and ExteriorWallWithWindow
Redesigned model to allow CFD implementation.

This revision added the changes needed to separate convection and radiation.
Redesigned model to allow CFD implementation.

This revision corrects a wrong assignment of the heat transfer area.
Updated script and corresponding variable in reference file.
Redesigned model to allow CFD implementation.

This revision assignes the linearize radiation flag.
Changed unused variable in plot command.
Updated reference files.

The change is due to a correction in the implementation of the convective heat transfer of the room-side frame. Only these two examples are affected by this change.
