Domain decomposition for the \(SP_N\) solver MINOS. (English) Zbl 1273.82081
This paper studies the \(SP_N\) transport equations by using a domain decomposition method based on the Schwarz iterative algorithm. The authors establish the convergence of the method and they develop an asymptotic method to optimize the choice of the Robin matrices that appear in the interface conditions of Robin type. The numerical experiments are done by using the MINOS solver.
