Abstract
In this article we present a domain decomposition method for the mixed SPN equations, discretized with Raviart-Thomas-Nédélec finite elements. This domain decomposition is based on the iterative Schwarz algorithm with Robin interface conditions to handle communications. After having described this method, we give details on how to optimize the convergence. Finally, we give some numerical results computed in a realistic 3D domain. The computations are done with the MINOS solver of the APOLLO3® code.
本文给出了用raviart - thomas - nsamdsamlec有限元离散的混合SPN方程的一种区域分解方法。该领域分解基于迭代Schwarz算法，采用Robin接口条件处理通信。在描述了这种方法之后，我们详细说明了如何优化收敛性。最后给出了在实际三维环境下的数值计算结果。计算是用APOLLO3®代码的MINOS求解器完成的。
