VANT. Ser.: Mat. Mod. Fiz. Proc 2012. Вып.2. С. 51-63.

The applicability domain of the algorithm of coalescence of kinetic equation and P1-approximation radiation transfer equation was analyzed. The definition of inner boundary conditions at coalescence point is considered. The automatic selection criterion for coalescence point is suggested. The applicability of the algorithm suggested was analyzed in terms of a number of method problems.

Keywords: radiation transfer, P1-approximation, coalescence.
