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 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. It was in this context that the term was coined by citation needed]

[edit] CAE fields and phases

CAE areas covered include:

In general, there are three phases in any computer-aided engineering task:

  • Pre-processing – defining the model and environmental factors to be applied to it. (typically a finite element model, but facet, voxel and thin sheet methods are also used)
  • Analysis solver (usually performed on high powered computers)
  • Post-processing of results (using visualization tools)

This cycle is iterated, often many times, either manually or with the use of commercial optimization software.

[edit] CAE in the automotive industry

CAE tools are very widely used in the prototype testing. CAE dependability is based upon all proper assumptions as inputs and must identify critical inputs (BJ). Even though there have been many advances in CAE, and it is widely used in the engineering field, physical testing is still used as a final confirmation for subsystems due to the fact that CAE cannot predict all variables in complex assemblies (i.e. metal stretch, thinning).
