In a product design and analysis process, engineers have different usage views towards product information models.The heterogeneous transformation problem has been presented to characterize the resulting gap between design models and analysis models. The multi-representation architecture (MRA) has been developed to realize this transformation through four stepping-stone information representations, including analyzable product models, context-based analysis models, analysis building blocks (ABBs), and solution method models (SMMs).

In this paper, our primary focus is on ABBs for solid mechanics and thermal systems that generate FEA SMMs to obtain their results. ABBs, which represent the analytical usage view for analysis engineers, are constructed using object-oriented knowledge representation known as constrained objects (COBs). ABBs represent product-independent analysis concepts such as continuum mechanics bodies and idealized interconnections as semantically rich, reusable, modular, and tool-independent objects. To demonstrate the efficacy of the ABB model, an electronic chip package thermomechanical analysis test case is overviewed. This extended ABB approach provides an effective way to capture engineering knowledge and decrease FEA modeling time.
