Finite element analysis has become the most popular technique for
studying engineering structures in detail. It is particularly
useful whenever the complexity of the geometry or of the loading is
such that alternative methods are inappropriate. The finite element
method is based on the premise that a complex structure can be
broken down into finitely many smaller pieces (elements), the
behaviour of each of which is known or can be postulated. These
elements might then be assembled in some sense to model the
behaviour of the structure. Intuitively this premise seems
reasonable, but there are many important questions that need to be
answered. In order to answer them it is necessary to apply a degree
of mathematical rigour to the development of finite element
techniques. The approach that will be taken in this book is to
develop the fundamental ideas and methodologies based on an
intuitive engineering approach, and then to support them with
appropriate mathematical proofs where necessary. It will rapidly
become clear that the finite element method is an extremely
powerful tool for the analysis of structures (and for other field
problems), but that the volume of calculations required to solve
all but the most trivial of them is such that the assistance of a
computer is necessary. As stated above, many questions arise
concerning finite element analysis. Some of these questions are
associated with the fundamental mathematical formulations, some
with numerical solution techniques, and others with the practical
application of the method. In order to answer these questions, the
engineer/analyst needs to understand both the nature and
limitations of the finite element approximation and the fundamental
behaviour of the structure. Misapplication of finite element
analysis programs is most likely to arise when the analyst is
ignorant of engineering phenomena.

Multiphysics Simulations in Automotive and Aerospace Applications
provides the fundamentals and latest developments on numerical
methods for solving multiphysics problems, including fluid-solid
interaction, fluid-structure-thermal coupling,
electromagnetic-fluid-solid coupling, vibro and aeroacoustics.
Chapters describe the different algorithms and numerical methods
used for solving coupled problems using implicit or explicit
coupling problems from industrial or academic applications. Given
the book's comprehensive coverage, automotive and aerospace
engineers, designers, graduate students and researchers involved in
the simulation of practical coupling problems will find the book
useful in its approach.
Multiphysics Modelling of Fluid-Particulate Systems provides an
explanation of how to model fluid-particulate systems using
Eulerian and Lagrangian methods. The computational cost and
relative merits of the different methods are compared, with
recommendations on where and how to apply them provided. The
science underlying the fluid-particulate phenomena involves
computational fluid dynamics (for liquids and gases), computational
particle dynamics (solids), and mass and heat transfer. In order to
simulate these systems, it is essential to model the interactions
between phases and the fluids and particles themselves. This book
details instructions for several numerical methods of dealing with
this complex problem. This book is essential reading for
researchers from all backgrounds interested in multiphase flows or
fluid-solid modeling, as well as engineers working on related
problems in chemical engineering, food science, process
engineering, geophysics or metallurgical processing.
