Managing Simulation. As CAE moves to earlier portions of the design process, it is morphing into simulation and becoming more of a “what-if” tool. Simulation is ultimately what we are trying to achieve – a working model for exploration at the front end of design. For complex products, to achieve the benefits of this “what-if” tool, large numbers of parts and assemblies and configurations present a big challenge when assessing the potential impact of a proposed change. Even for not-so-complex products, the amount of information that needs to be analyzed after the simulation is large and must be managed. MSC, Ansys, Dassault Systemes, UGS, and others are starting to address this need with a new class of tool. Who needs it? What are the issues involved?
