Computer-aided engineering (CAE) embraces the application of computers from preliminary design (CAD) through production (CAM). Computer-aided design (CAD), which is usually associated with computerized drafting applications, also includes such diverse application programs such as those for calculating the dimensional stack-ups due to tolerances, ergonomic studies with virtual people, and design optimization. Computer-aided analysis (CAA) includes finite element and finite difference methods for solving the partial differential equations governing solid mechanics, fluid mechanics, and heat transfer, but it also includes diverse programs for specialized analyses such as rigid body dynamics and control system modeling. Computer-aided manufacturing (CAM) includes programs for generating the instructions for computer numerically controlled (CNC) machining to production and process scheduling and inventory control. Recently, manufacturers have been asked to design their products for eventual recycling, and this aspect of engineering will undoubtedly fall under the umbrella of CAE, but as of yet, it doesn't have its own acronym. Software used worldwide by many of the largest OEM's for CAE Analysis in the automotive, aerospace, manufacturing and other industries is LS-DYNA, a general purpose transient dynamic finite element program capable of simulating complex real world problems. Applications include:
