Abstract
A method is developed for constructing the conformal map of a distorted region onto a rectangle. A discrete Fourier transform is used to map the boundary of the region onto the boundary of the rectangle; the resulting equations may be solved using a fast Fourier transform algorithm. The map for internal points may then be constructed using a standard Laplace equation solver. The method is computationally competitive, and is applicable to field problems, for instance in fluid mechanics.
