Summary
In this paper, development of the three-dimensional structural analysis is performed by applying FETI-local method.
In the FETI-local method, the penalty term is added as a preconditioner. The OPT-DKT shell element is used in the
present structural analysis. Newmark-beta method is employed to conduct the dynamic analysis. The three-dimensional
FETI-local static structural analysis is conducted. The contour and the displacement of the results are compared
following the different number of sub-domains. The computational time and memory usage are compared with respect to
the number of CPUs used. The three-dimensional dynamic structural analysis is conducted while applying FETI-local
method. The present results show appropriate scalability in terms of the computational time and memory usage. It is
expected to improve the computational efficiency by combining the advantages of the original FETI method, i.e.,
FETI-mixed using the mixed local-global Lagrange multiplier.
