English abstract:
We present a modelling strategy based on the finite element method to describe flexible, piezoelectric structures surrounded bya compressible fluid, including viscosity. Non-conforming interfaces based on the Mortar method are used to couple the differentphysical domains. Finally, we present an application example of a piezoelectrically actuated MEMS structure to illustrate the modelingprocedure and the impact of viscous effects.

Wir präsentieren eine Finite Elemente-Modellierungsstrategie für flexible und piezoelektrisch erregte Strukturen, welche von einemviskosen, kompressiblen Fluid umgeben sind. Die unterschiedlichen Bereiche werden anhand der Nitsche-Methode für nicht-konformeGitter miteinander gekoppelt. Ein abschließendes Anwendungsbeispiel einer piezoelekt
