Over the past two decades, efficient methods of grid generation, together with the
power of modern digital computers, have been the key to the development of numerical
finite-difference (as well as finite-volume and finite-element) solutions of linear
and non-linear partial differential equations in regions with boundaries of complex
shape. Although much of this development has been directed toward fluid mechanics
problems, the techniques are equally applicable to other fields of physics and engineering
where field solutions are important. Structured grid generation is, broadly
speaking, concerned with the construction of co-ordinate systems which provide coordinate
curves (in two dimensions) and co-ordinate surfaces (in three dimensions)
that remain coincident with the boundaries of the solution domain in a given problem.
Grid points then arise in the interior of the solution domain at the intersection of these
curves or surfaces, the grid cells, lying between pairs of intersecting adjacent curves
or surfaces, being generally four-sided figures in two dimensions and small volumes
with six curved faces in three dimensions.
