Clustering Results Around Peaks for Full-Harmonic Analyses in ANSYS
  Aaron Acton (ANSYS, Inc.)
  "This article presents a method for obtaining full harmonic solutions clustered around potential peak responses. Full harmonic analyses provide exact solutions, typically calculated at equally spaced intervals over the desired frequency range. Mode-superposition analyses, however, provide approximate solutions, but can be clustered around potential resonant peaks. The hybrid method discussed in this article uses a modal solution to determine natural frequencies, which are then used to calculate clusters of points surrounding those frequencies. Full harmonic solutions can then be performed at these clustered points. Examples and input les are provided in order to utilize this method."
