Gray, L. J.

A subroutine for solving the interior three dimensional LaPlace equation del/sup 2/ V = 0 by the boundary element method is described. The bounding surface is defined by triangular elements, each element defined by three nodes (vertices) in appropriate order for calculating the outward normal. The boundary data at a boundary node P is either the value of the potential V(P) or the normal derivative of V(P). The required integrals over the triangular elements are computed using linear interpolation from the nodal values. This routine has been especially tailored in several ways for use in modeling electrochemical processes.
