Member Data Documentation

Yleft

double ConvectionSystemY::Yleft

Mass fraction to the left of the domain.

Used only in conjuction with BoundaryCondition::ControlVolume.

k

size_t ConvectionSystemY::k

Species index.

Used for debugging purposes only.

splitConst

dvec ConvectionSystemY::splitConst

constant term introduced by splitting

vInterp

true when solving the quasi-2d problem; false otherwise.

v

dvec ConvectionSystemY::v

private

The velocity normal to the flame [m/s].
