A systematic introduction to partial differential

equations and modern finite element methods for their efficient
numerical solution

Partial Differential Equations and the Finite Element Method
provides a much-needed, clear, and systematic introduction to
modern theory of partial differential equations (PDEs) and finite
element methods (FEM). Both nodal and hierachic concepts of the FEM
are examined. Reflecting the growing complexity and multiscale
nature of current engineering and scientific problems, the author
emphasizes higher-order finite element methods such as the spectral
or hp-FEM.

A solid introduction to the theory of PDEs and FEM contained in
Chapters 1-4 serves as the core and foundation of the publication.
Chapter 5 is devoted to modern higher-order methods for the
numerical solution of ordinary differential equations (ODEs) that
arise in the semidiscretization of time-dependent PDEs by the
Method of Lines (MOL). Chapter 6 discusses fourth-order PDEs rooted
in the bending of elastic beams and plates and approximates their
solution by means of higher-order Hermite and Argyris elements.
Finally, Chapter 7 introduces the reader to various PDEs governing
computational electromagnetics and describes their finite element
approximation, including modern higher-order edge elements for
Maxwell's equations.

The understanding of many theoretical and practical aspects of both
PDEs and FEM requires a solid knowledge of linear algebra and
elementary functional analysis, such as functions and linear
operators in the Lebesgue, Hilbert, and Sobolev spaces. These
topics are discussed with the help of many illustrative examples in
Appendix A, which is provided as a service for those readers who
need to gain the necessary background or require a refresher
tutorial. Appendix B presents several finite element computations
rooted in practical engineering problems and demonstrates the
benefits of using higher-order FEM.

Numerous finite element algorithms are written out in detail
alongside implementation discussions. Exercises, including many
that involve programming the FEM, are designed to assist the reader
in solving typical problems in engineering and science.

Specifically designed as a coursebook, this student-tested
publication is geared to upper-level undergraduates and graduate
students in all disciplines of computational engineeringand
science. It is also a practical problem-solving reference for
researchers, engineers, and physicists.
