Course detail

Computer Aided Technology

FSI-DPPAcad. year: 2026/2027

The course acquaints students with the possibilities of computer aid in various areas of manufacturing design, especially with the use of numerical simulation and finite element method (FEM) as a tool 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 a basic orientation in the field of numerical simulations and analyses using the finite element method.
