Abstract : In this paper, hybrid direct-iterative linear solution method is proposed to solve large-scalestructural analysis problem. Direct solution method is common to finite element structuralanalysis, but it has some disadvantage compared with iterative method. Iterative method isquite good performance to solve large scale problem, so we can combine both two method toget good performance to solve the structural analysis problem. Hybrid method proposed inthis paper is based on Additive-Schwarz domain decomposition method, generally used tovarious scientific and engineering fields that need high performance computing. Wholeproblem domain is divided into some piece of subdomains and each internal domain is solvedby multifrontal direct method. Additive-Schwarz domain decomposition with multifrontalmethod is used as preconditioner of Conjugate Gradient. We can good result and performancepoint of view convergence speed by proposed method.
