A method is proposed for numerically solving the integro-differential, 
radiative-transfer equation with the use of its piecewise-analytic 
solutions obtained by the discrete-ordinate method and grids constructed 
by the finite-element method. The advantages of the method proposed 
and some results of calculation of the radiative-transfer characteristics 
for one-, two-, and three-dimensional problems are discussed.
