Detailed Description

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

Diffusion of the pressure correction, with a diagonal (single-equation) coefficient.

Note

The equation has no convective term at all, so the solver runs this kernel with ScalarFluxOptions::convective cleared and the inherited CUpwScalarFlux::finalizeFlux is never reached; see CPoissonSolver::Viscous_Residual.

The diffusion coefficient is the momentum coefficient vol/A_p carried by the solver's own variables, not a flow primitive, so nothing here reads the flow's primitive row; the flow variables are only asked which points carry a strong velocity BC.

Momentum coefficient, an i/j average, identical for both edge sides (TSL Jacobian).

Note

A point under a strong velocity BC has no momentum equation; its coefficient is the average of its neighbours' (see CPoissonSolver::SetMomCoeff).
