Functions/Subroutines
subroutine, public	s_compute_slip_wall_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	The L variables for the slip wall CBC, see pg. 451 of Thompson (1990). At the slip wall (frictionless wall), the normal component of velocity is zero at all times, while the transverse velocities may be nonzero.
subroutine, public	s_compute_nonreflecting_subsonic_buffer_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	The L variables for the nonreflecting subsonic buffer CBC see pg. 13 of Thompson (1987). The nonreflecting subsonic buffer reduces the amplitude of any reflections caused by outgoing waves.
subroutine, public	s_compute_nonreflecting_subsonic_inflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	The L variables for the nonreflecting subsonic inflow CBC see pg. 455, Thompson (1990). This nonreflecting subsonic CBC assumes an incoming flow and reduces the amplitude of any reflections caused by outgoing waves.
subroutine, public	s_compute_nonreflecting_subsonic_outflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	The L variables for the nonreflecting subsonic outflow CBC see pg. 454 of Thompson (1990). This nonreflecting subsonic CBC presumes an outgoing flow and reduces the amplitude of any reflections caused by outgoing waves.
subroutine, public	s_compute_force_free_subsonic_outflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	The L variables for the force-free subsonic outflow CBC, see pg. 454 of Thompson (1990). The force-free subsonic outflow sets to zero the sum of all of the forces which are acting on a fluid element for the normal coordinate direction to the boundary. As a result, a fluid element at the boundary is simply advected outward at the fluid velocity.
subroutine, public	s_compute_constant_pressure_subsonic_outflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	L variables for the constant pressure subsonic outflow CBC see pg. 455 Thompson (1990). The constant pressure subsonic outflow maintains a fixed pressure at the CBC boundary in absence of any transverse effects.
subroutine, public	s_compute_supersonic_inflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	L variables for the supersonic inflow CBC, see pg. 453 Thompson (1990). The supersonic inflow CBC is a steady state, or nearly a steady state, CBC in which only the transverse terms may generate a time dependence at the inflow boundary.
subroutine, public	s_compute_supersonic_outflow_l (lambda, l, rho, c, mf, dalpha_rho_ds, dpres_ds, dvel_ds, dadv_ds)
	L variables for the supersonic outflow CBC, see pg. 453 of Thompson (1990). For the supersonic outflow CBC, the flow evolution at the boundary is determined completely by the interior data.
