$$\text{CAE [ Computer Aided Engineering ]}$$

$\rightarrow$ CAE retrives description and geometry from a CAD database

$\rightarrow$ It is used in almost every industry such as manufacturing, aespace, automobile, defence etc.

$\rightarrow$ CAE depends on CAD

$\rightarrow$ CAE is an engineering analysis performed at the computer terminal using a CAD system.

$\underline{\text{Advantages}}$

1. It increases production efficiency and quality through better designs.
2. Executives and managers heavily rely on CAE analysis.
3. Tool for decision making - what the product is going to look like, its performance characteristics.
4. What improvements need to be made?
5. Provide the customers withj a concept before building expensive prototypes and pre- production units.
6. Products tested for any possible conditions you can think of.
7. Optimization of the concept.
8. Conceptual design through analysis.
9. Final results of analysis help to reduce future costs.
10. Great savings in time and money.
11. Ensures achievment of customer satisfaction.

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

1. Pre-processing $\rightarrow$ defining the geometry model, the physical model and the boundary conditions.
2. Computing $\rightarrow$ Usually performed on high powered computers (HPC)
3. Post-processing (of results) $\rightarrow$ using scientific visualization tools & techniques.

The cycle is iterated, often many times, either manually or with the use of automation techniques or using optimization software.

CAE is applied in these 4 main types of analysis

1. Finite Element Analysis (FEA)
2. Computational Fluid Dynamics (CFD)
3. Boundary Element Analysis (BEA/Acoustics)
4. Kinematic/Dynamic Analysis
