These Skills are mediated in the CAE workshops
3 10.07.2014
Mediation of crucial practical skills in the domain of construction and optimization which are substantial for engineers today
Learn to handle common CAE tools Prepare students for computational tasks
Modelling and abstraction Generating simulation modells Interpreting results Present and defend results
Acquisition of personal for the institute (thesis, student assistants, academic trainees etc.)

Main topics of the CAE-Workshops Application of the learned knowledge
iprod - CAE workshop at IPEK - Dipl.-Ing. Markus Spadinger
Theoretical basics, e.g. technical mechanics are deepened during the engineering studies The practical application of this knowledge is coming off badly frequently
Idea: give the students the opportunity to work on their own, but supervised on computational and optimization tasks The theoretical basics are put into an application-oriented context, the understanding is deepened and the meaning is recognized

Main topics of the CAE-Workshops Practice-orientation
iprod - CAE workshop at IPEK - Dipl.-Ing. Markus Spadinger
The tasks are structured in a way, that focuses on application-oriented examples
The students work on problems computational engineers periodically deal with in their everyday working life Sensitization for possible challenges in the model preparation in case the model does not conform to a academically idealized example The students realize the relevance of the lecture and their interest is intensified by practice-oriented outstanding feedback

Main topics of the CAE-Workshops Interpretation and Presentation of the results
iprod - CAE workshop at IPEK - Dipl.-Ing. Markus Spadinger
Scenario: a group of computational engineers has to present their computation results to the client
Computational engineers = students client = supervising assistant and paricipants
Task: Explain the problem and the modelling Present and interpret the results Discussion
Intense examination with the following questions:
• What do I have to do and what do I want to figure out? • How do I arrive at a good result? • How do I interpret my results and its quality? • How can I interpret a colleague's result?
