How are power circuit designers making use of computerized fluid dynamics in dealing with heat problems? John Parry, Electronics Industry Manager at the Mentor Graphics Mechanical Analysis Div., talks about how much designers need to know about CFD to get useful results, the accuracy of new "simplified" CFD methods, what happens when CFD packages must work with different kinds of CAD models, and much more. Parry has 30 years experience applying 3D CFD methods to numerous areas of electronics.
