Abstract : In this paper, hybrid direct-iterative linear solution method is proposed to solve largescalestructural analysis problem. Direct solution method is common to finite elementstructural analysis, but it has some disadvantage compared with iterative method.Iterative method is quite good performance to solve large scale problem, so we cancombine both two method to get good performance to solve the structural analysisproblem. Hybrid method proposed in this paper is based on FETI-DP method which is akind of iterative substructuring domain decomposition method. Whole problem domainis divided into some piece of subdomains and each internal domain is solved bymultifrontal direct method and interface variables are treated by iterative solutionmethod. We will show good result and performance point of view convergence speedby proposed method.
