Course detail

Simulation of Technological Processes

FSI-HPR-KAcad. year: 2024/2025

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.

Rules for evaluation and completion of the course

The final evaluation is based on the elaboration of assigned numerical analyses within the work with the selected software and proof of theoretical knowledge in the form of a written test. It is classified by using the ECTS grading scale.


Attendance in lectures is recommended. Attendance in exercises is compulsory. The attendance to the seminar is regularly checked and the participation in the lesson is recorded. In case, that the lesson does not possible to participate, the teacher may in justified cases set an additional assignment.

Aims

Aim of the course is to acquaint students with the nature, possibilities of the use and application field of basic methods of numerical modelling, especially in solving the design and optimization of technological processes associated with metal forming, welding and heat treatment. The course also aims to acquire the skills necessary to work with simulation software in these areas.

 

Students will be acquainted with theory as well as with the latest knowledge in the field of numerical simulations currently used in technical practice. They will acquire necessary skills for formulation and solution of computational models in the areas of forming, welding and heat treatment.
