Abstract A parallel simulation user environment (PSUE) has been developed for unstructured grid‐based computational simulation. Arbitrary computer application software can be integrated into the environment to provide a multi‐disciplinary engineering analysis capability within one unified computational framework. It provides an enhanced capability for complex and multiple problem definition, a graphics environment for guidance through the grid generation process with visual validation of each step, and robust and computationally efficient unstructured grid generation modules. This paper addresses an interactive geometry utility environment (IGUE), which is the primary part of the PSUE, providing sophisticated graphical user interfaces with geometric handling capability oriented to the unstructured grid technology. The IGUE is equipped with windowing functionality from the X‐Window system, and its underpinning data structure is based on non‐manifold topology. Copyright © 2001 John Wiley & Sons, Ltd.
