Details The students independently solve tasks in which given physical arrangements are to be calculated with an FEM programme. Subsequently, a report is written in the form of a conference paper.
The examinations during the course consist of three tasks with different scope and correspondingly different influence on the grade:
1. Simulation of two electrostatic arrangements. Exploitation of model symmetries. (20 %)
2. Simulation and optimisation of a magnetic arrangement with materials with linear and non-linear magnetisation characteristic. (20 %)
3. Automation of a simulation of a magnetic arrangement with Python and calculation of characteristics by parameter variation and output to a diagram. (60 %)

Minimum standard - Functional simulation with physically meaningful results.
- Comprehensible presentation of the results in the respective report.
- Achievement of 50% of the total points to be awarded.
