WebAn eigenfrequency study solves for the eigenfrequencies (natural frequencies) and the shapes of the corresponding eigenmodes. When performing an eigenfrequency analysis, you can specify whether to look at the mathematically more fundamental eigenvalue, λ, or the eigenfrequency, f, which is more commonly used in a structural mechanics context. WebOct 4, 2024 · The basic idea underlying eigenvalue finding algorithms is called power iteration, and it is a simple one. Start with any vector , and continually multiply by . Suppose, for the moment, that this process converges to some vector (it almost certainly does not, but we will fix that in soon). Call the limit vector . Then must satisfy 3
