Teaching language

Suitable for English-speaking students

Objectives

The student will master the fundamental concepts of numerical methods and will have the ability to perform numerical modeling of technological processes such as bulk metal forming and sheet metal forming, by using commercial codes and related pre and post processing tools.

Learning outcomes and competences

By the end of the semester, students should:

1. be acquainted with the methods used in numerical modeling programs;

2. be able to use pre-processing, analysis and post-processing tools, which are necessary to the numerical simulation as well as being able to develop specific programming tools to efficiently obtain the numerical model and specific results;

3. be able to create the numerical model of applications to technological processes, performing the analysis and getting results in parallel with a critical evaluation. Also, student should be able to suggest directions for improvements in order to avoid defects by selecting or changing processing variables and optimizing the process.
