Abstract
In this paper we investigate the performance of some mixed finite elements used in the displacement/pressure (u/p) and displacement-pressure-vorticity moment (u-p-Λ) formulations for acoustic fluid-structure interactions. In particular, we show that certain elements pass a numerical inf-sup test and are valuable for general applications. Also considered are macroelements that are based on simple four-node elements.Keywords
