Detailed Description

Sets the ghost state to the provided freestream state.

Technically this can result in an ill-posed problem if used in anything other than a supersonic inlet, but in numerical practice it often gets you the right answer anyway, at least for inviscid problems.

Member Function Documentation

apply_flux()

void hexed::Freestream::apply_flux ( Boundary_face & )

virtual

applies boundary condition to viscous fluxes (if applicable)

Implements hexed::Flow_bc.

apply_state()

void hexed::Freestream::apply_state ( Boundary_face & )

virtual

applies boundary condition to state variables (Dirichlet BCs)

writes to the first n_var()*size() entries of ghost_state() (called on the provided Boundary_face.)

Implements hexed::Flow_bc.
