Computer aided engineering (CAE) is an analysis performed at the computer terminal using a CAD system. It includes computer-aided design (CAD), computer-aided analysis (CAA), computer-integrated manufacturing (CIM), computer-aided manufacturing (CAM), material requirements planning (MRP), and computer-aided planning (CAP). Its purpose is mainly to analyze the different materials, products, their performance and quality, such as durability, stability, etc. It has many advantages like improved safety and product quality, reduced product cost, customer satisfaction, etc. and so it has many applications like used to analyze the properties of material, commercial and flight simulations, etc. It has 3 phases: pre-processing, analysis solver, post- processing of results.
CAE is mainly of 3 types: finite element analysis (FEA), computational fluid dynamics (CFD), and Boundary Element Analysis (BEA). FEA is used to conduct static and dynamic analysis. CFD is used to optimize components for efficient fluid flow and heat transfer. BEA is used to predict noise characteristics on various systems. One of the real world examples is MEMS that is micro electro mechanical systems. It has the size of a grain of salt or the eye of a needle.
The future success of a manufacturing enterprise is likely to be determined by the speed and efficiency with which it incorporates new technologies into its operations. The process which is currently used to engineer, or re-engineer, manufacturing systems is often ad hoc. Computerized tools are used on a very limited basis. Given the costs and resources involved in the construction and operation of manufacturing systems, the engineering process must be made more scientific. Powerful new computing environments for engineering manufacturing systems could help achieve that objective.
Today, Computer Aided Engineering (CAE) technology contributes decisively to shortening and optimizing product development cycles in many fields of industry and research. Computer aided analysis and simulation enables our customers to assess and test the behaviour of future components, products and processes by subjecting them to a range of computer simulated physical conditions.This leads to savings in both the time and money which would have been spent on cost-intensive test runs without any loss in quality and opens up new possibilities for innovation.
Computer aided engineering (CAE) retrieves description and geometry from a computer aided manufacturing (CAD) database. Computer aided engineering (CAE) is an analysis performed at the computer terminal using a CAD system. Thus software tools that have been developed to support the activities in computer analysis are considered CAE tools. CAE tools are being used, for example, to analyze the robustness and performance of components and assemblies. The term encompasses simulation, validation, and optimization of products and manufacturing tools. In the future, CAE systems will be major providers of information to help support design teams in decision making. In regard to information networks, CAE systems are individually considered a single node on a total information network and each node may interact with other nodes on the network. CAE systems can provide support to businesses. This is achieved by the use of reference architectures and their ability to place information views on the business process. Reference architecture is the basis from which information model, especially product and manufacturing models. The term CAE has also been used by some in the past to describe the use of computer technology within engineering in a broader sense than just engineering analysis.
CAE is an analysis entirely done on computer using CAD systems. Its purpose is to analyze different materials, products, their performance and quality such as durability, stability, endurance and/or reactivity to any possible factor that can affect the performance of the material, part, and/or the product A typical CAE process comprises of pre-processing, solving, and post-processing steps. In the pre-processing phase, engineers model the geometry and the physical properties of the design, as well as the environment in the form of applied loads or constraints. Next, the model is solved using an appropriate mathematical formulation of the underlying physics. In the post-processing phase, the results are presented to the engineer for review. The analysis of CAE consists of mainly 4 methods like finite element analysis, computational fluid dynamics, boundary element analysis, kinematic and dynamic analysis. It has many advantages like its cost saving and ensures customer satisfaction and improves the speed, efficiency and the quality of many products ranging from simple parts to vehicles, airplanes etc. Designs can be evaluated and refined using computer simulations. Its applications include control systems analysis, simulation of manufacturing processes like casting, moulding and die press forming, Optimization of the product or process.
