Abstract
This paper describes the use of exact values in the solution of boundary el-
ement problems and compares the accuracy of the corresponding numerical
solutions with those obtained using the traditional interpolation method.
The new scheme improves accuracy significantly, perhaps by several orders
of magnitude, at little computational cost.
1 Introduction
The traditional approach to solving a boundary element problem over a
domain il with boundary conditions $ defined over a boundary F has been to
take the geometry of F, discretise this geometry and use a set of polynomial
interpolation functions to represent each section of the discretised shape.
The assembly of entries in the coefficient matrices then consists of using
these
