The Workload of the module sums up to 180.0 Hours. Therefore the module contains 6 Credits.

Description of Teaching and Learning Methods

The module consists of the lecture and exercises. The exercises are mostly done at computers, either using Python (for basic computations) or a finite element software package (for more complex tasks). Each participant is assigned a specific computation problem to be solved and support is given to do the necessary numerical computations. In the end a written report is to be submitted which is also the basis for the grade.
