Description

Abstract A program to compute the spectral harmonic expansion coefficients of the product of two triangular truncated scalar fields is presented. The calculations are performed by a transform method which is more computer efficient relative to the traditional interaction coefficient approach or finite-difference method. Title of program: VCSUM Catalogue Id: ABHK_v1_0 Nature of problem There is a wide range of applications of spectral method in solving partial differential equations in mathematical physics. Versions of this program held in the CPC repository in Mendeley Data ABHK_v1_0; VCSUM; 10.1016/0010-4655(89)90043-X This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
