1.4 Advantages of Finite Element Method 11

We will follow the above procedure, step by step, to
analyze different types of problems in the following chapters.
These include structural, heat transfer and fluid flow problems
using one-, two- and three-dimensional finite element models. We
will find that, if we performed each step correctly, the ANSYS
Workbench will show the check mark symbol ( ) on the right side
of the step. But if we see other symbols, we need to go back and
fix that step before moving on. The process thus ensures us that
everything has been done appropriately before obtaining the final
solutions.

1.4 Advantages of Finite Element Method

The finite element method is popular and widely used
by scientists and engineers all over the world for analyzing various
types of problems. Examples of problems are as follows.

(a) Stress analyses of large-scale structures such as bridges,
ships, trains, aircrafts, automobiles and buildings.
Structural analysis for small-scale products are such as
automotive and electronic parts, furniture, machine
equipment, etc.

(b) Vibration and dynamic analyses of high-voltage power
transmission towers, expressway signs under strong
wind, crash simulation of automobiles, turbine blades
operating under high pressure and temperature, etc.

(c) Fluid analyses of air flows over cities, air ventilation in
large halls, inside offices, cleanrooms, computer cases,
etc.

(d) Electromagnetic analyses around power transmission
lines, electric motors, sensitive electronic devices, etc.

(e) Bio-mechanic analyses of blood flow in human hearts
and veins, artificial joints and bones, etc.
