o All the physical phenomena can be modeled by differential equations or governing equations.
o A differential equation can be solved by classical analytical methods or numerical methods.
o However, complexities in the geometry, properties and in the boundary conditions that are seen in most real-world problems usually means that an exact solution cannot be obtained or obtained in a reasonable amount of time.
Background
o Current product design cycle times imply that engineers must obtain design solutions in a „short‟ amount of time.
o They are content to obtain approximate solutions that can be readily obtained in a reasonable time frame, and with reasonable effort. The CAE is one such approximate solution technique.
o The CAE is a numerical procedure for obtaining approximate solutions to many of the problems encountered in engineering analysis.

CAE is Virtual Testing Find Weakness Reduce Wight Increase Strength Optimize Performance Vary Materials Check Factor of Safety More…..
Basic Theory of CAE is FEA/FEM (Finite Element Analysis/Finite Element
Methods
CAE is the technology concerned with the use of computer system to analysis CAD geometry, allowing designer to simulate and study how the product will behave so that the design can be refined and optimized.

What is CAE ?
![Page 14: Präsentation Defect Reducing Based Computer Aidid Engineering-edit](https://reader030.fdocuments.in/reader030/viewer/2022032516/563dbacb550346aa9aa81864/html5/thumbnails/14.jpg)
What is FEA/FEM ?o FEA/FEM is one of
numerical methods to attain approximate solution of governing equation by dividing a large region into small sub-regions
o The sub-regions are called finite elements
o The process of dividing is called meshing
precision is my friend
o FEA/FEM is a computer model of a material or design that can be used in ;
1. new product design2. existing product
refinement 3. simulating structural
failure 4. investigating point of
interest not accessible in reality, e.g., internal structure
5. and more
o Design analysis: hand calculations, experiments, and computer simulations
o FEM/FEA is the most widely applied computer simulation method in engineering
o Closely integrated with CAD/CAM applications
