ABSTRACT

In the special case where L1x = L'ly, the grid aspect ratio f3 is unity, and Eqs. (9.60) and (9.61) become

(9.62)

(9.63)

Equations (9.60) to (9.63) are analogous to Eqs. (9.22) to (9.26) presented in Section 9.4 for solving the Laplace equation numerically. All the general features of the numerical solution of the Laplace equation presented in Sections 9.4 to 9.7 apply directly to the numerical solution of the Poisson equation.
