User S Guide to a Boundary Element Package for Solving Integral Equations on Piecewise Smooth Surfaces

This guide describes a collection of programs for creating and re ning triangulations on surfaces and solving integral equations using collocation methods over these tri angulations The main purpose of this package is to allow for experimentation with numerical methods for solving boundary integral equations that are de ned on piecewise smooth surfaces in R For a general survey of the numerical solution of boundary inte gral equation reformulations of Laplace s equation see The package is restricted to triangulations which are uniform But we are developing additional routines to allow for the use of graded meshes in solving boundary integral equations on surfaces for which the unknown density function has poor behaviour near edges and corners of the surface
