Introduction of optional geometrical attributes to:

Agreed in Workshop Munich by Thomas, Georgio, Alexandru, Silvia, Jerome, KH

JoachimBenner commented 8 years ago

I principally agree. However, it must be explained that the geometrical representations are not independent: The surfaceGeometry representation of all ThermalBoundary objects belonging to a ThermalZone define the volumeGeometry of this ThermalZone. What is the relation with the properties netVolume and grossVolume, which of these properties corresponds to the volumeGeometry?

RomainNouvel commented 8 years ago

In term of types: netVolume and grossVolume are two official measures, contrary to volumeGeometry which is a solid. During last workshop, there was a consensus to consider the external dimension of the wall as thermalZone boundaries. Then, the measure corresponding to the volumeGeometry is the grossVolume. Concerning your first point, we should clarify that in the documentation, however this does not lead to restriction or new relationships in the UML scheme. Moreover, since they are optional, a ThermalZone may have a volumeGeometry although its ThermalBoundary have no surfaceGeometry
