摘要
提出了一种既可随意布置离散方向 ,又能满足 90°旋转对称要求的新的离散坐标格式 ,其基本思路是 :先将每个卦限中的单位球表面划分为三个相等的部分 ,再在其中一部分内根据需要任意地布置离散方向 ,然后根据对称性得到其他两部分内的设置 .
A discrete ordinate scheme is proposed whose discrete directions not only can be arbitrarily adjusted, but also are invariant after any rotation of 90°. The procedures for designing this scheme are as follows: to divide the surface of the unit sphere in each octant into three symmetric parts, in one of the three parts, to arbitrarily arrange discrete directions advantageous to the radiation problem at hand, and to arrange the discrete directions in the other two parts according to the symmetry. The Numerical results demonstrate that the present scheme is accurate.
