| Abstract: | Eigenvalue and frequency response calculations are ubiquitous in scientific modeling and engineering analysis. Algebraic substructuring (AS) method is a powerful numerical technique for solving extremely large scale problems. We developed a unified framework and AS code that can solve both problems efficiently. Furthermore, we addressed some of the open problems in this field, including resolving arbitrary eigenmodes, performing high frequency response analysis, accuracy and performance.
