INDUSTRY & ENGINEERING

Many engineering companies, especially those in industrialized nations, have begun to
incorporate computer-aided engineering (CAE) programs into their existing design and
analysis processes, including 2D and 3D solid modeling computer-aided design (CAD). This
method has many benefits, including easier and more exhaustive visualization of products,
the ability to create virtual assemblies of parts, and the ease of use in designing mating
interfaces and tolerances.
Other CAE programs commonly used by engineers include product lifecycle management
(PLM) tools and analysis tools used to perform complex simulations. Analysis tools
may be used to predict product response to expected loads, including fatigue life and
manufacturability. These tools include finite element analysis (FEA), computational fluid
dynamics (CFD), and computer-aided manufacturing (CAM).
Using CAE programs, a mechanical design team can quickly and cheaply iterate the design
process to develop a product that better meets cost, performance, and other constraints. No
physical prototype need be created until the design nears completion, allowing hundreds or
thousands of designs to be evaluated, instead of a relative few. In addition, CAE analysis
programs can model complicated physical phenomena which cannot be solved by hand, such
as viscoelasticity, complex contact between mating parts, or non-Newtonian flows
As engineering begins to merge with other disciplines, as seen in mechatronics,
multidisciplinary design optimization (MDO) is being used with other CAE programs to
automate and improve the iterative design process. MDO tools wrap around existing CAE
processes, allowing product evaluation to continue even after the analyst goes home for the
day. They also utilize sophisticated optimization algorithms to more intelligently explore
possible designs, often finding better, innovative solutions to difficult multidisciplinary
design problems.
Computer-aided engineering (CAE) is the scientific application of a set of tools and
methods to a system which is meant to result in high-quality, defect-free, and maintainable
engineering products. It also refers to methods for the development of information systems
together with automated tools that can be used in the software and hardware development
process.

Computer engineering industry has an enormous impact over the economy of any country, as today's modern technological advancements are largely dependent on computer engineering industry. Over time, this industry is booming in such a way, that it may exceed all expectations.
