Learning outcomes of the course unit

An overview will be provided of the principles characterizing the methods for numerical modelling of electromagnetic fields. On this basis, the students will be able to:
- explain the numerical modelling methods
- perform a numerical analysis of simpler problems related to the electrostatic field, the steady-state electric field in conductive materials, the stationary and quasistatic electromagnetic fields.
- set up a numerical model for combined coupled problems (electromechanical, electrothermal).

Prerequisites

Students wishing to enroll in the course should be able to explain the basic notions and physical principles of electromagnetism, and they ought to have a basic understanding of the mathematical notation of partial differential equations. In the course-based discussions, the participants are expected to assess the consequences of electromagnetic principles and/or effects.
