5 Simulation Driven Product Development Instead of just using engineering simulation for verification or trouble-shooting, many companies are turning to Simulation Driven Product Development (SDPD) Design, simulate, optimize Physically test only the best candidates The benefits of SDPD Better performing products Shorter development times Reduced development costs 10X 100X Productivity Gain Customer needs Business drivers Technology trends 2010 ANSYS, Inc.

7 Today s Objectives Through this seminar we hope to demonstrate how each of these various simulation tools are extremely useful in addressing specific questions In addition we want to introduce how these tools, when coupled together, open up further possibilities to provide additional fidelity by including more physics into the engineering simulation To facilitate our customers to perform coupled simulations using the various ANSYS software, we have developed a framework called Workbench 2010 ANSYS, Inc.
