Major domains of CAE
• AutoCAD, ProE, SolidWorks
• Analysis software such as ANSYS, Abacus,
Nastran, Hypermesh, CFX etc.
• These are used from spread sheets to complex
finite element analysis problems such as
structural, thermal, electro-magnetic, heat
transfer, fluid flow and vibration problems.

Major domains of CAE
• The power of the spreadsheet is based on its ability to
automatically recalculate results when new inputs have
been entered in some cells.
• Other equation solver tools are TK Solver, MathCAD, and
Eureka.
• Another important set of computational tools are that
manipulate the symbols representing the equation are
Mathematica, Maple, and MatLab.
• These include software for finite-element modeling,
QFD, creativity enhancement, decision making, and
statistical modeling.
2. Mathematical analysis and simulation of design problems

Computer Aided Engineering
• A typical CAE software is made up of a number of
mathematical models encoded by algorithms written
in a programming language.
• The natural phenomena being analyzed are
represented by an engineering model. The physical
configuration is described by a geometric model.
• The results, together with the geometry are made
visible via a user interface on the display device and a
rendering model .

Application of CAE
Most surveying functions, such as triangulation and
elevation computations are now computerized, with data
being collected in computer form in the field via
electronic instruments. Map making and analysis are also
largely computerized now-a-days.
Civil Engineering:

8. DR. E. HEMACHANDRAN, IIITDM KURNOOL
Many electrical applications outside the tools discussed
make use of specialized tools for control system design
and simulations. CAE aids engineers in testing simulated
designs for control systems or other electronic devices to
see how they operate before committing to
manufacturing. In most cases, the computer simulation
replaces altogether the building of a prototype.
Application of CAE
Electrical and Electronics Engineering:

9. DR. E. HEMACHANDRAN, IIITDM KURNOOL
• The benefits of CAE include reduced product
development cost and time, with improved product
quality and durability.
• Design decisions can be made based on their impact
on performance.
• Designs can be evaluated and refined using computer
simulations rather than physical prototype testing,
saving money and time.
• Provide performance insights in the early stages of the
development process, when design changes are less
expensive to make.
Application of CAE
In Production application:

10. DR. E. HEMACHANDRAN, IIITDM KURNOOL
• Helps engineering teams manage risk and understand the
performance implications, product behaviors and
problems of their designs before it is put into production.
• Integrated CAE data and process management extends
the ability to effectively leverage performance insights
and improve designs to a broader community
• Warranty exposure is reduced by identifying and
eliminating potential problems. When properly integrated
into product and manufacturing development, CAE can
enable earlier problem resolution, which can dramatically
reduce the costs associated with the product lifecycle

• Finally, through a computer-based information system,
the designer can share more information sooner with
people in the company, like manufacturing engineers,
process planners, tool and die designers, and purchasing
agents.
• Further it also acts as the link between computer-aided
design (CAD) and computer-aided manufacturing (CAM).
Moreover, by using the Internet and satellite
telecommunication, these persons can be on different
continents also.
