Parallel Eigen Frequency Analysis Using Enriched Free Mesh Method

Abstract:

The Enriched Free Mesh Method (EFMM) is a Mixed Method using the Hellinger-Reissner principle. A highly accurate stiffness matrix is computed for each local cluster. As a result, the EFMM can compute the high performance structural problem of low-order mode without an increase in the number of DOF. In this research, a large eigen frequency analysis of discrete model of the EFMM is performed using the Lanczos method on a PC cluster environment.
