“For simulation-driven design, this is a necessary step to make simulation tools part of the design process,” says Walsh. It involves integrating simulation features in CAD design packages and simplifying input fields to set up simulation runs. The user interface must be reengineered to suit the target audience. Software Ease of Use: Vendors Get A-, B+įor designers to use simulation tools in the conceptual design phase, tools need to be easily accessible. We asked Joe Walsh, founder of IntrinSIM and director of Analysis, Simulation & Systems Engineering Software Strategies (ASSESS), to assign grades to each enabler. For this article, Digital Engineering decided to single out three enabling factors: (1) ease of use of simulation applications (2) user adoption and (3) access to computing power: Are these pillars of simulation-driven design as solid as the financial argument? Though the financial argument is solid, several forces must converge to make the mantra a reality. On top of that, add another $1 million to build a physical aircraft model ( “Symbiosis: Why CFD and wind tunnels need each other,” Joe Stumpe, June 2018, Aerospace America, published by AIAA). According to Boeing’s Department of Aeronautics and Astronautics, a typical wind tunnel session takes about 45 hours, at a price tag of $40K. In aerospace and automotive, the economics clearly favor virtual tests. This was driven in part by the software vendors’ proposition that virtual tests are much easier and cheaper than destructive physical tests. Simulation-driven design became the engineering community’s mantra in the last decade.
