Analysis model visualization and graphical analysis attribute specification system

A visual environment for defining and manipulating engineering analysis information has been developed. This environment: (i) allows queries and modifications of the topology and geometry that defines a geometric model obtained from various geometric modeling systems, (ii) abstracts the modeler's functionality needed to associate analysis information, (iii) provides a hierarchical attribute association model, and (iv) gives a graphical user interface to both the geometric modeler abstraction and attribute management system. Finally graphical issues relating to performance, portability and flexibility of different workstation environments are discussed.
