Abstract:
The use of Simulation in the design and development process is rapidly increasing. Companies are simulating more processes and products, in an increasing number of ways. Also, there is a trend towards modelling much larger systems to more accurately capture complex physical interactions. One problem which remains unsolved is how these many types of analyses can be handled in an integrated and coherent manner alongside CAD technologies. In this work a concept termed 'Simulation Intent' is introduced which helps to alleviate the CAD/CAE integration problem. Simulation Intent captures the modelling and idealisation decisions required to create a fit-for-purpose analysis model. Simulation Intent is defined in a high-level manner, making it robust to significant changes in the base geometric model. Furthermore, multiple definitions of Simulation Intent can be applied to produce different analysis models which are all linked in a coherent manner to the base geometric model. Three technologies are integral to the concept; Cellular Modelling, Equivalencing and Virtual Topology. Given the novelty of the approach, multiple examples are provided to demonstrate its application. It is shown that by using Cellular Modelling, system interfaces can be easily extracted and used in analysis modelling. , These Cellular Models are created and stored through the use of Virtual Topology meaning the base topology of the original geometric model remains unperturbed. Equivalencing offers the ability to apply boundary conditions, loads and connections at multiple levels of detail and dimensionality. Some ideas for future work are presented, which may help to progress the concept to full industrial realisation. The application to Method's Engineering in large companies is highlighted as one significant operational benefit. Simulation Intent offers a way to directly apply the correct analysis methods in the correct situations.
