利用牛顿技术求解特征值响应矩阵方程

SERMENT is a developmental response matrix code for solving reactor eigenvalue problems, using both classical power iteration and Jacobian-Free Newton-Krylov methods. SERMENT currently uses 2-d diffusion as its underlying transport kernel, and has been used successfully for a number of benchmarks. Current development is focusing on transport-based responses, alternative preconditioners, and coarse-grained parallelism. See the "Downloads" link for a recent paper and corresponding presentation giving an overview of our approach and some preliminary results.
