Detailed Description

template<class Double, class FlowIndices, int nDim, size_t nVar = 1>
class CScalarFlux_Heat< Double, FlowIndices, nDim, nVar >

Convection and diffusion of temperature, non-conservative, with a diagonal (single-equation) diffusion coefficient.

Note

The temperature has no notion of density weighting, so Conservative is false and the inherited CUpwScalarFlux::finalizeFlux, flux(0) = a0*phi_i(0) + a1*phi_j(0), is exactly the model's whole convective term; no override is needed.

The solver runs in two modes, weakly-coupled energy equation on a fluid zone or standalone conduction on a solid one (CHeatSolver::flow); the diffusion coefficient is the flow's thermal conductivity over specific heat, plus a turbulent contribution, in the former, and the configured constant thermal diffusivity in the latter. EdgeSide::flowNodes is null in the solid case, so this is the only place that may read it, and only when flow is set.
