18. CAE
Computer-Aided Engineering is the use of computer software to solve
engineering problems with the improvement of graphics displays, engineering
workstations, and graphics standards.
Engineers also use computer programs to estimate the performance and cost of
design prototypes and to calculate the optimal values for design parameters.
When combined with CAD, these automated analysis and optimization
capabilities are called computer-aided engineering (CAE)
Software Used: Ansys Workbench, Ansys APDL, Ansys Fluent.

19. Goals of CAE
The goals of computer-aided engineering (CAE) include:
Improved product quality and safety
Reduced engineering time, achieved through fewer design iterations
Improved product functionality and usability
Reduced number of prototypes, ultimately leading to their elimination in
many cases
Reduced product cost

20. Scenarios and Applications of CAE
Mechanical Engineering
1. Finite Element Analysis (FEA):
Structural analysis of a component’s behaviour under various kinds of
applied loads and supports e.g. Beam and Grid structures.
Thermal analysis of a structure’s behaviour when it is subjected to heating
and cooling.
Combined structural and thermal analysis.
Fluid mechanics analysis of the flow of fluids, such as air, water, and
lubricants around the surfaces of an object. Pressure, fluid velocity, and
other factors can be determined

Mechanical Engineering
2. Mechanism Analysis:
Mechanism analysis studies the behaviour of mechanical systems
undergoing motion. Typically, the geometry, mass, inertia, compliance,
stiffness, and damping of the system’s components as well as the forces
and loads applied from outside the system must be defined. Equations
of motion are developed and solved. The results of the analysis may
include positions, velocities, accelerations, forces (applied, reactive, and
inertial), determination of equilibrium positions, and other computed
parameters.
