On a generalised alternating direction implicit method for solving Laplace's equation
Department of Computational and Statistical Science, The University, Liverpool, UK
This paper describes a generalized A.D.I. scheme involving an extra parameter which is equivalent to Guittet's scheme for solving Laplace's equation over an m-dimensional supercube. In addition the model problem in the 3-dimensional case is treated but the method using the alternative generalisation is applied with the parameter sequence of Douglas, unlike Guittet's which has a fixed parameter.
