summary 
Finite element methods are introduced for the approximate solution of periodic acoustic problems. A least squares technique is used for those problems which are governed by a first order system of partial differential equations while for second order equations, a Galerkin/multigrid technique is employed. In both cases, the solution process for the algebraic system resulting from discretization is iterative in character
