Pa survey of numerical methods for acoustics, namely the finite element method (FEM) and the boundary element method (BEM). This book summarizes FEM and BEM (and optimization) for acoustics. It shows that both methods can be effectively used for many other cases, FEM even for open domains and BEM for closed ones.
