Abstract : A recurring problem in solid state physics is that of determining the electrostatic field or potential at a point within the crystal lattice arising from the molecules of the lattice themselves. A typical problem is that of finding the electrostatic binding potential of an ionic lattice assuming point charges. Work was performed toward perfecting a method for calculating the electric field arising from a lattice of dipoles. This work culminated in a paper detailing a procedure which ensures a rapidly converging summation of the three dimensional lattice sums involved. The present paper is an extension of the latter, presenting a computer program for evaluating dipole fields in a crystal lattice.
