Abstract

Abstract

In this paper, spacial domain-decomposed parallel Matrix MOC and relevant multi-domain coupled PGMRES accelerating algorithm were studied. In this algorithm, PGMRES from PETSc library was adopted to solve the angular flux of inner boundaries directly, thus improving the convergence rate. Numerical results demonstrated that the multi-domain coupled PGMRES algorithm keeps good accuracy and obtains great speed ratio.
