In the years to come, CAD will steadily improve engineering productivity by speeding the design process, suggesting options along the way, and identifying problems earlier. The software will “think” for designers and anticipate what they are creating. Finite element analysis (FEA) and Computational Fluid Dynamics (CFD) are widely used engineering analysis techniques in the world today. Engineers employ FEA & CFD to simulate how a physical system (usually an engineered product or manufacturing process) will respond to expected loading conditions. Practical applications of FEA & CFD include structural analysis of bridges and buildings, impact or crash analysis of automobiles, aerodynamic analysis of airplanes and airfoils, electromagnetic analysis of AC and DC motors, injection molding simulation of plastic parts, fluid flow analysis in channels and pipes and heat transfer through residential and commercial buildings.
