◆ absorb

template<class T>

Matrix<double> line::fluid::FluidImmediateMatrix< T >::absorb

Projector for the initial condition: identity on the timed rows, the absorption distribution on the immediate ones.

Mass parked on an eliminated coordinate would otherwise be frozen there for the whole integration.

◆ eliminated

template<class T>

bool line::fluid::FluidImmediateMatrix< T >::eliminated = false

◆ emap

template<class T>

Matrix<double> line::fluid::FluidImmediateMatrix< T >::emap

emap(e, o): expected firings of the ORIGINAL event o per firing of the reduced event e; the identity when nothing was eliminated.

A caller maps a per-event quantity with new = emap * old, which is what lets a throughput read off a reduced event set stay exact – an event folded through an immediate coordinate is a completion at more than one (station,class).
