1. Introduction:
For many years, ANSYS has 2D and 3D acoustic elements, including those used to model an “infinite” boundary. These elements can be used in modal, harmonic, and transient analyses, and fluid-structural interaction can also be accounted for in these simulations.
This memo hopes to review the following topics related to harmonic acoustic analyses: basic comparison of structural and acoustic elements, modeling complex impedance boundary conditions, and defining complex pressure loading. A set of input files, which analyze the case of a simple radiating sphere, is included with this memo |
