Abstract : A computer software system has been developed to automatically generate twodimensional 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 multisurface 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.
