This is a collection of programs for solving a boundary integral equation reformulation of the interior Dirichlet problems for Laplace's equation in R3. The programs are described in the paper

K. Atkinson, Algorithm 629: An integral equation program for Laplace's equation in three dimensions, ACM Transactions on Mathematical Software 11 (1985), pp. 85-96.

Generalizations have been written for other boundary integral equation problems, and the author should be contacted directly for information about these programs, at

You can access a general introduction, the program gnrt.f (to generate the Galerkin coefficients), and the program dirichlet_3d.f (to solve the interior Dirichlet problem).
