Preface to the Third Edition

The third edition of this book fully preserves the character of the previous editions to combine physical modeling of mechatronic systems and their numerical simulation using the Finite Element (FE) method. Most of the text and general appearance of the previous editions were retained, while the topics have been strongly extended and the presentation improved. Thereby, the third edition contains the following main extensions: • • • • • •

Finite elements of higher order Flexible discretization towards non-conforming methods Computational fluid dynamics and coupled fluid-solid-interaction (FSI) Perfectly matched layer (PML) technique in time domain Comprehensive discussion of aeroacoustics with latest numerical schemes Advanced numerical schemes for piezoelectricity including macro- and micromechanical models.

We have enhanced the basic chapter concerning the Finite Element (FE) method by now providing the FE basis functions and integration points for all geometric elements (quadrilateral, triangle, tetrahedron, hexahedron, wedge and pyramid). Furthermore, we discuss in detail p-FEM (finite elements of higher order
