The Finite Element Method
The Finite Element Method (FEM) belongs to the broad class of variational methods, and so it is natural to start this chapter with an introduction and overview of such methods. This section emphasizes the importance of the variational approach to computation: it can be claimed — with only a small bit of exaggeration — that all numerical methods are variational.
