Aim
The course presents methods for solving physical problems that are described by partial differential equations. The student should be given a physical insight and be able to use this in order to mathematically formulate the problems. The course gives an introduction to electromagnetic field theory and to areas where the theory is applied. The projects in the course aim at giving the student an experience in solving comprehensive physical problems.
Knowledge and understanding
For a passing grade the student must
- know and understand the basics of field theory, electromagnetism, and the finite element method.
- be able to apply Maxwells equations to simple electrostatic, magnetostatic, and electrodynamic problems.
- be able to apply the finite element method to problems in electrostatics, magnetostatics and heat conduction
Skills and abilities
For a passing grade the student must
- know how to use basic vector analysis in Cartesian and curvilinear coordinate systems.
- be able to determine the electric and magnetic fields and forces in simple problems.
- be able to determine induced currents and voltages in simple cases.
- be able to treat plane electromagnetic waves mathematically.
- know how to make the transformation from strong to weak form.
- know how to establish the finite element formulation from the weak form.
- be able to write a finite element method program.
Judgement and approach
For a passing grade the student must
- have the ability to analyse and simulate physical problems, and to interpret and present the results.
- understand that technical and physical problems from different areas can be analysed and simulated with the same methods.
