Detailed Description

Kinetic to 5 Moment Flux Boundary Condition This sets the numerical flux that for the fluid model at the boundary interface between the fluid and kinetic model.

It is the summation of the flux determined from the intermediate interface distribution that is constructed from the part of the kinetic distribution going into the fluid domain and the part of the Maxwellian distribution on the fluid side that is going into the kinetic domain

This is the boundary condition for the fluid flux coming from the kinetic domain For continuity: (F dot n)* = (rho V) dot n = ((A int (vf) dv)_f2k + A int (vf) dv)_k2f) dot n f2k is the fluid to kinetic part k2f is the kinetic to fluid part int (vf) dv is simply the first moment calculated in another app, but it does not include the A so we add this back in

For momentum: (F dot n)* = (rhoVV + P) dot n = ((int (Avvf) dv)_f2k + (int (Avvf) dv)_k2f) dot n (int (Avvf) dv) is the full dyadic second moment calculated in another app and includes A

For energy (F dot n)* = (eV + PV + h) dot n = ((int (1/2Avv^2f) dv)_f2k + (int (1/2Avv^2f) dv)_k2f) dot n int (1/2Avv^2f) dv is the energy flux moment calculated in another app and includes A

The normal should point from fluid to kinetic, because we are looking for the fluid numerical flux, which should be automatically the normal that we have because we are solving this on the fluid side with the kinetic side being the "right" or "outside" or "+".
