Detailed Description

Boundary condition for radiative heat flux in a linear finite volume system.

The outgoing radiative flux q = sigma * emissivity * (T^4 - Tinfinity^4) is linearized via first-order Taylor expansion around the extrapolated boundary face temperature T_b_old: T_b^4 ~ 4*T_b_old^3*T_b - 3*T_b_old^4 yielding a Robin BC: k * dT/dn + [4*sigma*eps*T_b_old^3]*T_b = [sigma*eps*(3*T_b_old^4 + Tinf^4)] with alpha=k, beta=4*sigma*eps*T_b_old^3, gamma=sigma*eps*(3*T_b_old^4+Tinf^4). Second-order spatial accuracy is achieved by extrapolating T_b_old to the face. The lagged coefficients are updated on each linear system assembly.
