Plattsum: A fortran program that evaluates electrostatic lattice sums by the planewise summation method

Title of program: PLATTSUM Catalogue Id: ABVT_v1_0 Nature of problem The calculation of the electrostatic potential due to a Bravais lattice of point charges presents several problems, of a practical as well as of a conceptual nature, coming from its convergence properties. Leaving aside the fact that the potential of an infinite charge distribution diverges, the numerical difficulties lie in the fact that the convergence of the sum is very slow.
