摘要
研究了求解中子输运方程的谱有限元方法.用球谐函数谱展开和间断Galerkin 有限元耦合方法求解Boltzmann 中子输运方程,证明了这种耦合方法的收敛性,并给出了误差估计,得到了比标准Galerkin 有限元方法更好的稳定性和收敛精度.
A spectral discontinuous finite element method is developed for solving the transport equation. Use are made of spherical function expansion and discontinuous Galerkin finite element method to construct an algorithm for studying the stability and convergence. Improvement is made when compared with the standard Galerkin method.
