A modification to PLATTSUM, a program that evaluates electrostatic lattice sums by the planewise summation method

Title of program: PLATTSUM2 Catalogue Id: ABVT_v2_0 [ACKW] Nature of problem The input and output of the program PLATTSUM for evaluating electrostatic lattice sums have been modified in such a way as to reduce the manual work of the user when the calculation involves many field points and/or many source sublattices. Versions of this program held in the CPC repository in Mendeley Data ABVT_v1_0; PLATTSUM; 10.1016/0010-4655(81)90076-X ABVT_v2_0; PLATTSUM2; 10.1016/0010-4655(83)90081-4 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
