Finite Elementsved numerically. Chapter 6 gives a very basic introduction into the most popular numerical approach—Finite Elements Method (FEM). Chapter 7 will explore an alternative approach—Finite Differences Method (FDM), which has advantages for solution of non-linear and unstable boundary value problems.

Thanks to these features, this method: (a) is practically identical to the simple version of the FEM described in Chapter 6; (b) is more efficient in terms of computer memory and for solution of nonlinear problems.
