Electrostatic FieldsWith the approximation to Maxwell’s equations presented in the previous chapter, it is possible to decouple the equations in two groups. One group describes electrostatic phenomena, the other magnetic phenomena. In this chapter we look at the first group, and at the electrostatic fields it describes.

Galerkin’s Residual Method: Applications to Dynamic FieldsFor some type of problems, the search of functionals is difficult. For these, other methods, using the finite element technique, were developed. The most commonly used of these is the “Galerkin method”. It is a particular form of the more general “weighted residual” method, whose principles will be outlined later in this chapter.

At present, there is more interest in building complete computational software packages, providing simple use of the method for the project engineer, regardless of how familiar he may be with the finite element method. This also seems to be the t
