【 摘 要 】

Multigrid preconditioned conjugate gradient method is proposed for the algebraic systems resulting from two 8-node hexahedron combined hybrid elements with high performance for the linear elasticity problem. Numerical computations are presented, which demonstrate the convergence and effectiveness of the method.
