The intention of this book is to provide experienced engineers and project managers with an overview of the potential of multi-physics analysis.

The authors and co-authors attempt to illustrate the variety of application fields and the mixture of ‘mono-physics’ simulation disciplines which can be combined to give a multiphysics analysis.

Examples from various areas of research and industrial practice will show the necessity and the applicability of a multi-physics analysis. Without going into the details of the physical and numerical modelling, the reader should be able to obtain some idea of each of the multi-physics cases described and, hopefully, be able to apply some of these ideas to their own problem.

The objective of this book is not to specify details of the technical solutions for effecting multi-physics simulations, but to motivate the user to consider  multidisciplinary simulations relevant to their own working environment.

Our examination of the feasibility and applicability of multi-physics processes in this booklet are primarily restricted to the classical disciplines of continuum mechanics and its combinations:

- structural analysis and thermodynamics,

- fluid mechanics,

- acoustics,

- electro-magnetism.

Most examples cited in this booklet refer to numerical simulations using grid based discretisations.
