2. Finite element analysis (FEA) is a computerized method for
predicting how a product reacts to real-world forces, vibration,
heat, fluid flow, and other physical effects. Finite element analysis
shows whether a product will break, wear out, or work the way it
was designed. It is called analysis, but in the product development
process, it is used to predict what is going to happen when the
product is used.
FEA works by breaking down a real object into a large number
(thousands to hundreds of thousands) of finite elements, such as
little cubes. Mathematical equations help predict the behavior of
each element. A computer then adds up all the individual behaviors
to predict the behavior of the actual object.

3. What is Finite Element Analysis Software?
Finite element analysis helps predict the behavior of products
affected by many physical effects, including:
Mechanical
Stress
Mechanical
Vibration
Fatigue Motion
Heat
Transfer
Fluid flow Electrostatics
Plastic
injection
molding

4. What is ANSYS
• ANSYS is a general-purpose finite element analysis (FEA)
software package.
John A Swanson Founder of
ANSYS

5. THE BLACK BOX
• To understand how ANSYS works we use the Black Box
Theory. We consider that ANSYS is a Black Box
