Description of exams and course work
On the other hand a project work in the form of homework (programming exercice) are used to report the extent to which participants are able to develop vibro-acoustic models using ANSYS and Matlab and to apply stochastic FEM on their own. Besides the ability of modeling, the acquired knowledge of sFEM formulations will be asked in the homework. (50% )
There is a possibility to take the exam in the following semester.
