Q Tell me about the whole CAD integrated simulation I’m hearing a lot about?
A Well, it’s like this. Your 3D design system holds all of the information you need to define how a product appears in terms of aesthetics and functions in terms of fit. Simulation allows you to extend that representation to test how your product performs and then adjust and optimise it.
Q So I can build a functional prototype of my product before it gets anywhere near manufacturing?
A Essentially, yes. At the moment, simulation is divided into discrete subjects or functional areas (usually called “physics”). You can test its mechanical performance using Finite Element Analysis (FEA), you can simulate heat transfer and fluid flow using Computational Fluid Dynamics (CFD), you can simulate the motion of a product using kinematic analysis.
Q What’s the benefit of having these integrated into a single interface?
A The argument is that by placing these tools in the hands of the designer, for use during development, results in a better product – without having to have an expert in simulation on hand to do the number crunching work.
Q How realistic is that in the real world?
A That’s the key sticking point. Just because these tools are available to everyone doesn’t mean they’re going to be used properly. With simulation, there’s a problem with a lack of understanding of how to translate the knowledge designers and engineers have of their product and field of expertise and moving that into the world of simulation. It needs careful attention to ensure the tools are used properly and the results interpreted correctly. Otherwise it’s a waste of time.
