CUpwScalarFlux< Double, Derived, FlowIndices, nDim, nVar > Class Template Reference

Convective flux shared by every model whose transport equation has the shape flux(iVar) = a0 * w_i * phi_i(iVar) + a1 * w_j * phi_j(iVar), which is every model except SA and stochastic backscatter (see CScalarFlux_SA). More...

Detailed Description

template<class Double, class Derived, class FlowIndices, int nDim, size_t nVar>
class CUpwScalarFlux< Double, Derived, FlowIndices, nDim, nVar >

Convective flux shared by every model whose transport equation has the shape flux(iVar) = a0 * w_i * phi_i(iVar) + a1 * w_j * phi_j(iVar), which is every model except SA and stochastic backscatter (see CScalarFlux_SA).

Note

The weight w is 1 for a non-conservative model, the density for a conservative one.

Upwind convection of the transported variable, weighted by the density for a conservative model.

Parameters

[in]	phi	- Transported variable of both endpoints, reconstructed if opt.muscl is set; read from here rather than side_i/side_j.scalarNodes directly so a model needs no reconstruction logic of its own.
[in]	rho	- Density of both endpoints, reconstructed alongside the velocity when the convective scheme reconstructs, so it weights the flux as the velocity does.

Note

The flux is written in terms of the transported variable but the Jacobians are w.r.t. the conserved one, which for a conservative model is the density-weighted variable; the density therefore multiplies the flux and not the Jacobian.
