HeatStructureEnergyBase

Post-processors deriving from HeatStructureEnergyBase compute the total energy EtotE_{tot} stored in a heat structure: Etot=iNViρcpTdV, E_{tot} = \sum\limits_i^N \int\limits_{V_i} \rho c_p T dV \,,(1) where NN is the number of regions in the heat structure that are considered (i.e., the size of the parameter block), ρ\rho is the density, cpc_p is the isobaric specific heat capacity, TT is the temperature, and ViV_i is the spatial domain of region ii.

Optionally, one can supply a reference temperature T0T_0 (which is zero by default, yielding Eq. (1)) to compute the energy change: ΔEtot=iNViρcp(TT0)dV. \Delta E_{tot} = \sum\limits_i^N \int\limits_{V_i} \rho c_p (T - T_0) dV \,.(2)
