Solving Parallelly 3-D Neutron Diffusion Equation Based on HYPRE

摘要: 采用有限差分方法离散三维中子扩散方程，并通过常用的源迭代法求解k_eff，其中内迭代采用基于HYPRE的并行共轭梯度法。对IAEA3D基准题的数值计算结果表明，该方法取得了较高的并行效率。

Abstract: Finite difference method was used to solve 3-D neutron diffusion equation, and k_eff was acquired by power iteration. The inner-iteration adopted parallel conjugate gradient method based on HYPRE. The numerical test results show good parallel efficiency.
