The course is composed of two parts of equal length (each 12h + 12h).

Part 1.The physics behind the Maxwell equations are briefly recalled and the equations for electrostatics, electrodynamics, magnetostatics and magnetodynamics are derived and explained. This includes induced currents from motion and varying magnetic fields.

Also the (laminar) Navier-Stokes equations for incompressible flow and the energy conservation equation are recalled and complemented with electromagnetic terms such that fully coupled thermal-electromagnetic problems are within reach. Finally the balance equations for transport of ions in electrolytes are given.

 

Based on the weighted residual method, and mainly applied to the Laplace equation, it is shown how the different discretisation techniques are derived and linked. We treat the finite element method (FEM), the boundary element method (BEM), the residual distribution method (RDM), the finite difference method (FDM) and a family of analytical methods.

 

We also treat the following numerical aspects:

·       non-linear boundary conditions (as encountered in electrochemical problems)

·       non-linear media (magnetic material)

·       iteration methods

·       calculation of derived quantities such as total current and flux.

 

The practical exercises start with the analysis of the global structure of a boundary element and finite element program. The students are next confronted with existing software in order to experience the fundamental properties of elliptic fields (boundary effects, sphere of influence, …). Finally the students are asked to solve a particular electrotechnical problem.



Part 2. The modelling of electromagnetic actuators and electric machines is studied considering the following aspects:



·       particular 2D and 3D formulations



·       electrical circuit coupling, distinguishing between stranded and massive conductors



·       modelling of movement of rotation



·       force and torque calculation



·       magnetic material modelling



·       optimisation



This material will be illustrated by means of a number of test cases and practical exercises for the students.

Algemene competenties



The general introduction on the equations gives a broad scientific knowledge and understanding into the links between the quasi-static magnetic field and electric field systems and conservation equations for energy, mass and momentum. This allows formulating and designing complex coupled systems that can be simplified.

In the second part concerning the practical modeling of electromagnetic devices ample attention is paid to both numerical accuracy and good engineering pragmatism. The flexibility, large appliability and limitations of the used software is put into evidence.

We give a very general overview of the different numerical methds that are available and commonly used to solve field problems (electric and magnetic fields, temperature, concentration). The focus is on a generic approach that provides a global link between the different discretization methods such that they can even be combined. In this way we give a global background to model complex problems rather than focusing on the usage of existing software packages (Magnet, Cosmos, Comsol, ....
