Component Modes Synthesis Method with Multiple Partitions for Large-scale Eigenvalue Problem
SessionNumerical Geometry a la Mode
DescriptionTo solve ultra-large-scale modal analysis problems, we extend Component Mode Synthesis (CMS) methods to use multiple partitions to generate more efficient local eigenbasis functions and reduce the computational cost of the low-frequency interface modes. We obtained the lowest 1500 eigenmodes of a model (30M DoFs) in 88 minutes.
