Abstract: The method is applied to solve the large linear equations when the finite element method is used.When blocks method is used,coefficient matrix of equations is triangulated and is stored by a dimension change bandwidth.The exchange data are carried out between EMS memory, and external memory.The method saves EMS memory,improves computational efficiency,and overcomes the problems of EMS memory.Some numerical results show that the method is more efficient than the others.

Key words: Finite element method,Triangle reduce method,Blocks method
