This model distinguishes between internal
thermal masses and exterior walls. While exterior walls contribute to heat
transfer to the ambient, adiabatic conditions apply to internal masses.
Parameters for the internal wall element are the length of the RC-chain
nInt, the vector of the capacities
CInt[nInt] and the vector of the resistances RInt[nInt].
This approach allows considering the dynamic behaviour induced by internal
heat storage.
The image below shows the RC-network of this model.
