The Boundary Element Method in Acoustics

The boundary element method (BEM) is a powerful computational technique, pro-
viding numerical solutions to a range of scientific and engineering problems. To the
user, the main characteristic of the method is that only a mesh of the boundary of
the domain is required. Hence, at the very least, the method is easier to apply than
the more traditional finite element method.
The subject of this text is the development of boundary element methods for the
solution of problems in linear acoustics. Three classes of problem are considered:
Chapter 4 - interior acoustic problems, Chapter 5 - exterior acoustic problems and
Chapter 6 - the modal analysis of an enclosed fluid. Each class of problem is considered
in three domain settings: two-dimensions, three-dimensions and axisymmetry.
