Abstract

The local interface formulation for nonlinear dynamic analysis of large structures is presented using domain decomposition and preconditioned conjugate gradient (PCG) technique. In the formulation, the PCG algorithm is formulated using the unassembled local Schur complement matrices of subdomains. Incomplete Cholesky preconditioner is employed. Newmark- average acceleration technique is employed for time integration. Numerical results indicate that the proposed parallel formulation is superior in performance when compared to the conventional domain decomposition algorithms with parallel direct solver.
