| Summary |
|---|
| The course is devoted to the basics of modelling and simulation in the field of materials engineering. Attention is paid to mathematical and physical modelling and simulations, especially for the most important processes and / or technological operations that take place in important engineering materials. Students will be acquainted with the possibilities of modelling and simulation of crystallization processes, materials processing (forming, heat treatment, welding, etc.). Students will learn how to work with some software packages used in engineering practice. Physical modelling will also be part of the course, especially in the case of time-dependent degradation processes. Emphasis will be placed on possible limits of modelling and simulation and on the need of experimental verification of simulation and modelling results. |
| Learning Outcomes of the Course Unit |
