Time and cost benefits of engineering simulation are this simulation method has the potential to reduce crack well documented. Predicting product performance and growth analysis time by over 90 percent compared determining optimal solutions early in the design phase help with manual methods. The productivity gain will enable to avoid late-stage problems and to eliminate trial-and-error engineers to analyze more designs annually, thus keeping testing cycles that drive up costs and bog down schedules. up with increased demand for turbochargers around the Simulation enables engineers to perform what-if studies world and strengthening the company’s leadership and to compare alternatives, processes that otherwise position in this competitive industry sector. would be impractical. Indeed, bottom-line savings are The prediction method is based on improved fracture one key benefit that prompts most companies to implement mechanics capabilities for calculating J integrals, one of simulation, and are most readily quantified in return-on- the many enhancements in ANSYS 12.0. Previewed in the investment calculations. Spotlight section of this issue, the release is a milestone A second, and potentially greater, benefit is boosting for the software supplier and a huge step forward for the top-line revenue growth. With simulation, companies can CAE industry in terms of advancements in individual develop innovative, winning products that stand apart from physics (structural, fluid, thermal and electromagnetics) others, make the status quo obsolete or create entirely new and integration of this functionality into a unified multi- market opportunities. Brand value can be enhanced physics framework for Simulation Driven Product by tuning product performance to specific performance Development — an approach leading to top-line revenue characteristics. Revenue streams may be expanded by growth and bottom-line savings for many companies. increasing design throughput of new products or tackling Discussion of the business value of simulation is projects that otherwise would not be attempted. particularly relevant in today’s world as manufacturers How specific companies leverage simulation in face the toughest economic climate of a lifetime. Indeed, achieving these benefits depends on their unique products, with their survival at stake, forward-thinking companies engineering challenges and business requirements. The recognize the need to invest in engineering simulation now possibilities are limitless. Case in point is detailed in this more than ever to withstand the current market turbulence issue’s article “Predicting 3-D Fatigue Cracks without a and to strengthen their long-term competitive position, Crystal Ball” from Honeywell Turbo Technologies. Engineers brand value and profitability as conditions improve in the used software from ANSYS to predict thermomechanical coming years. ■ fatigue cracks in turbochargers for internal combustion engines. Predicting crack failures early enables engineers to optimize designs upfront and helps to avoid qualification test failures that lead to additional rounds of tests — which can be very expensive and take weeks to complete.
