Abstract
The Boundary Element Method is a technique which offers
important advantage over domain type solutions. One of the
most interesting features of the method is the much smaller
systems of equations and considerable reduction of the data
required to run a problem. This method is also well suited to problem solving with infinite domains. It is used to indicate
the method whereby the external surface of the domain is divided into a series of elements over which the functions
under consideration can vary in different ways. The boundary method can be formulated in terms of influence functions and
as such as frequently found in the literature under the
general title Boundary Integral Method.
In the present work the boundary element technique is
applied to solve steady and time dependent problems. Time
dependent linear elliptic partial differential equations are
solved in two dimensions using potential method. This
effectively reduces the dimensionality of the problem
throughout the time domain. However, due to the presence of
the convective terms, domain integrals need also to be
computed. A theory based on the solution of a singular
integral equation is developed for calculating the frequency
