			'''Computer-aided engineering''' ('''CAE''') refers to the use of computer software to aid in engineering analysis tasks. It encompasses simulation, validation, and optimization of products and manufacturing tools. CAE is a broad term that includes [[finite element analysis]] (FEA), [[computational fluid dynamics]] (CFD), and [[multibody dynamics]] (MBD).

	== Applications ==		== Applications ==
	CAE finds applications in various industries, including automotive, aerospace, electronics, and manufacturing. In the automotive industry, CAE is used to simulate crash tests, optimize vehicle aerodynamics, and analyze engine performance. In aerospace, CAE is utilized for structural analysis, fluid dynamics simulations, and aircraft design. Electronics companies rely on CAE to design and analyze circuit boards, while manufacturers use it to optimize production processes and improve product quality.

	== ~~Tools and Techniques~~ ==		CAE is used in various fields of engineering to improve product design and performance. It allows engineers to simulate the behavior of products under different conditions, which helps in identifying potential issues before physical prototypes are made.

			=== Finite Element Analysis (FEA) ===

			[[Finite element analysis]] is a computational technique used to approximate the behavior of physical systems. It divides a large system into smaller, simpler parts called finite elements. The behavior of each element is described by equations, which are then assembled into a larger system of equations that models the entire problem.

			=== Computational Fluid Dynamics (CFD) ===

			[[Computational fluid dynamics]] is used to analyze fluid flow, heat transfer, and related phenomena. CFD uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows. It is widely used in the design of aircraft, automobiles, and other systems where fluid flow is a critical factor.

			=== Multibody Dynamics (MBD) ===

			[[Multibody dynamics]] involves the study of systems of interconnected bodies under the action of forces. It is used to analyze the motion of mechanical systems, such as vehicles, machinery, and robotics.

			== Benefits ==

			CAE provides several benefits, including:

	~~[[Finite Element Analysis (FEA)]]~~: ~~FEA is a numerical method used to solve complex engineering problems by dividing~~ the ~~system into smaller~~, ~~more manageable elements~~. ~~It is widely used~~ for ~~structural analysis~~, ~~heat transfer simulations~~, and ~~fluid flow analysis~~.		* '''Cost Reduction''': By simulating and testing designs virtually, companies can reduce the need for physical prototypes, saving time and money.
