Fh. Read, IMPROVED EXTRAPOLATION TECHNIQUE IN THE BOUNDARY-ELEMENT METHOD TO FIND THE CAPACITANCES OF THE UNIT SQUARE AND CUBE, Journal of computational physics, 133(1), 1997, pp. 1-5
Extrapolation of the number IV of subdivisions to infinity in the boun
dary element method involves fitting computed results to a polynomial
in 1/N. A technique of choosing the sizes of the subdivisions in such
a way that the terms of lowest order in 1/N are eliminated, giving a m
ore accurate extrapolation, is described. The technique is used to est
ablish the capacitances of the unit square and cube with relative erro
rs of 3 x 10(-7) and 3 x 10(-6) respectively. (C) 1997 Academic Press.
