- To remain a generic as possible, a heatport directly connected to the first discrete layer of the wall has been added. For specific applications, The ForcedConvection module or another module for modelling radiation can be latter connected to this empty heat port when implementing the HalfWall

- For the <b>CarrollRadiation</b> module, the HalfWall module proposes two approaches for passing information about the form factor.
-
- <h4> Explicit connection: <b>UseImplicitConnection = false</b> </h4>
-
- The HalfWall supplies as output the surface area of the wall, via its ports, to the FviewCalculator module and get from this last the Fview as input.
- The connection is performed explicitely via the graphic connector.
- The <b>RadiativeIndex</b> parameter is not evaluated.
- The explicit method is longer and is source of mistakes when manually selecting the index of the connection.
-
- <h4> Implicit connection: <b>UseImplicitConnection = true</b> </h4>
-
- The implicit connection use the <b>inner</b> and <b>outer</b> key word to perform the passage of information.
- The ports <b>Awall</b> and <b>Fview</b> have to remains without connection.
- The <b>FviewCalculator</b> is declared as outer within the HalfWall module.
- The equations corresponding to the 'connect' with graphic connection are done explicitely in the equation section.
- To connect severals walls to the FviewCalculator, a <b>RadiativeIndex</b> is added.
- The value of raditave index corresponds to the index of the current wall in the FviewCalculator.
- Therefore, each wall needs to have a different RadiativeIndex.

- The HalfWall supplies as output the surface area of the wall, via its ports, to the FviewCalculator module and get from this last the Fview as input.
- The connection is performed explicitely via the graphic connector.
- The <b>RadiativeIndex</b> parameter is not evaluated.
- The explicit method is longer and is source of mistakes when manually selecting the index of the connection.
-
- <h4> Implicit connection: <b>UseImplicitConnection = true</b> </h4>
-
- The implicit connection use the <b>inner</b> and <b>outer</b> key word to perform the passage of information.
- The ports <b>A_wall</b> and <b>F_view</b> have to remains without connection.
- The <b>fviewCalculator</b> is declared as outer within the Wall module.
- The equations corresponding to the 'connect' with graphic connection are done explicitely in the equation section.
- To connect severals walls to the fviewCalculator, a <b>RadiativeIndex</b> is added.
- The value of raditave index corresponds to the index of the current wall in the FviewCalculator.
