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 %) Translated with www.DeepL.com/Translator (free version) |
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. |
