consider a diagram of the two common branches of the general modeling
solution process as shown in Figure 1.1.
For many real-world problems, the second approach is in fact the
only possibility. For instance, suppose that the aim is to find the thermo-
mechanical stresses in an air-cooled turbine blade depicted in Figure 1.2.
Figure 1.3 shows the complex three-dimensional geometry of the
blade along with the combined thermal and mechanical loadings, which
makes the analysis of the blade a formidable task. Nevertheless, many
powerful commercial finite element packages are available that can be
implemented to perform this task with relative ease.
