Abstract
Although numerical analysis applications have proven to be effective and reasonably accurate, the effort required to develop the associated analysis models remains a challenging and time consuming task. While many meshing tools are currently available, decomposing and manipulating the design geometry and enhancing the topology for mesh construction are manual processes and place the heaviest demands on time in the analysis process. The need to generate these models for different disciplines, each requiring different modeling abstraction and fidelity levels, further restricts the ability to use these analyses in the design process. Coupling these models across disciplines presents additional challenges since they often have different levels of abstraction and may not share the same geometry. This proposal focuses on the development of an environment for multidisciplinary analysis modeling and mesh generation. It employs an underlying object-oriented architecture with a common mesh infrastructure that facilitates rapid development of analysis model geometry. It integrates geometric reasoning, feature suppression, and dimension reduction methods to support automating the construction of analysis model geometry topology for mesh generation. Structured and unstructured meshes (1D/2D/3D) representing various levels of modeling fidelity for conceptual, preliminary, and detailed analyses and for different physical domains are supported. It enables the coupling of analysis models and design geometry and supports data interoperability among different analyses. The framework facilitates rapid development and automation of analysis modeling processes, facilitating rapid simulation for design validation and optimization of product performance at the earliest stage of the engineering process
