Abstract : A computer software system has been developed to automatically generate two-dimensional coordinates from algebraic transformations. For topologically complex regions, a smooth assembly of thee transformations can be used to automatically produce a composite mesh where a general gridded format is retained. To readily obtain a desireable level of global mesh smoothness and to permit a maximum amount of mesh control, the application of local multi-surface transformations is emphasized. In the formation of the composite mesh, the boundaries for each transformation are either transmissive or the prescribed geometry of given physical objects.
