  • Convergence of Diagonally Relaxed Quasi Robust ICCG Method for Linear Systems in the Mesh Superposition method

抄録

Diagonally Relaxed Quasi RICCG method is known to-be a powerful linear solver for FEM analysis. In this article, we evaluate its convergence through numerical experiments for linear systems which appear in the mesh superposition method as compared with a variety of preconditioned CG methods.
