Computer Aided Technology
FSI-HPT Acad. year: 2024/2025 Winter semester
The course acquaints students with the possibilities of computer aid in various areas of manufacturing design, especially with the use of 3D optical measurement and numerical simulation as tools for analysis and optimization of technological processes. In the lectures, students are introduced to the nature of the use of computer aid and numerical simulations for solving stress-strain and temperature problems, which are closely related to the issues of forming and welding technologies. Exercises aim primarily at practical calculations and mastering the main principles of computational models creating. Therefore, students will gain an orientation in the field of numerical simulations and analyses using the finite element method.
