Electrostatic and magnetostatic numerical analysis using nodal and edge finite element

The main objective of this work is to simulate electromagnetic fields using the Finite Element Method. Even in the easiest case of electrostatic and magnetostatic numerical simulation some problems appear when the nodal finite element is used. It is difficult to model vector fields with scalar functions mainly in non-homogeneous materials. With the aim to solve these problems two types of techniques are tried: the nodal elements and the edge finite element that ensure the continuity of tangential components. Some simple electromagnetic numerical analysis problems like waveguides, with homogeneous and non-homogeneous materials, are performed using first the nodal finite elements and then the edge finite elements.
