Overview:
In this paper, hybrid direct-iterative linear solution method is proposed to solve large-scale structural analysis problem. Direct solution method is common to finite element structural analysis, but it has some disadvantage compared with iterative method. Iterative method is quite good performance to solve large scale problem, so they can combine both two method to get good performance to solve the structural analysis problem. Hybrid method proposed in this paper is based on FETI-DP method which is a kind of iterative substructuring domain decomposition method. Whole problem domain is divided into some piece of subdomains and each internal domain is solved by multifrontal direct method and interface variables are treated by iterative solution method.
