This is a sequel to the book “Programming the Boundary Element Method” by G. Beerpublished by Wiley in 2001. The scope of this book is different however and this is reflected in the title. Whereas the previous book concentrated on explaining the implementation of a limited range of problems into computer code and the emphasis was
on programming, in the current book the problems covered are xtended, the emphasis is on explaining the theory and computer code is not presented for all topics. The new topics
covered range from dynamics to piezo-electricity. However, the main idea, to provide an
explanation of the Boundary Element Method (BEM), that is easy for engineers and
scientists to follow, is retained. This is achieved by explaining some aspects of the method
in an engineering rather than mathematical way.
Another new feature of the book is that it deals with the implementation of the method
on parallel processing hardware. I. M. Smith, who has been involved in programming the
finite element method for decades, illustrates that the BEM is “embarrassingly
parallelisable”. It is shown that the conversion of the BEM programs to run efficiently on
parallel processing hardware is not too difficult and the results are very impressive, such
as solving a 20 000 element problem during a “coffee break”.
Due to the fact that, compared to the Finite Element Method, a significantly smaller
group of people are working in this field the development of the method is lagging
considerably behind. The often quoted comparison that the method is a “Cinderella”,
dominated by her “big sister”, the Finite Element Method, and whose beauty is hidden
away, is still true and we hope that the reader will see the beauty of the method in the
examples on industrial applications and the advanced topics presented at the end.
The book includes some innovative development work carried out by the small but
very active group at the Institute for Structural Analysis, Graz University of Technology,
Austria under the leadership of G. Beer. The main scope of their research is to further
develop the method, so that it can be applied to a much wider range of practical problems
in engineering, one particular application of interest being in the field of geotechnical
engineering, especially underground excavation.
