Aims of the course unit:
 
Learning outcomes and competences:
 
Prerequisites:

Basic knowledge of manufacturing technology and basic computer skills.
Course contents:

The course "Simulation of Technological Processes" follows the course "Computer Aided Technology" and is focused on expanding basic knowledge in the field of numerical modelling with a focus on forming, welding and heat treatment technologies. In the lectures, students are acquainted with the essence of basic numerical methods used in current technical practice and with the use of numerical modelling for solving the issues of forming, welding and heat treatment technologies. The practical part – exercises aim primarily at the general principles of the creation of computational models, designed for the analysis of technological processes. Thus, students gain knowledge for independent orientation in the problems of numerical simulations and analyse.
