| Summary: | Helmholtz equation is a well known differential equation. Most
boundary value problems involving this equation are either difficult
or impossible to solve analytically. In this study, we employ a dual
reciprocity boundary element method (DRBEM) to solve these problems.
On the boundary and in the region bounded by the boundary, a set of
collocation points is chosen for the DRBEM. The computational
algorithm requires setting up and solving a system of linear
algebraic equation of the form, AX = B, based on this set of
collocation points. The solution to the boundary value problem is
therefore approximated by the solution of the algebraic equations.
Examples are presented to test this method, and results obtained are
compared with their corresponding analytic solutions. |
