The course is intended to introduce students to the most important contemporary computational models applied in the development of modern powertrains and motor vehicles. Emphasis is placed on the mathematical and physical basics of computational models and software tools, as well as the verification of computational modelling results by adequate experimental methods. The presented problematics includes applications of the finite element method in the analysis of deformation, stress, fatigue safety, temperature or contacts of motor vehicle components.

The course is taught through lectures explaining the basic principles and theory of the discipline.
Exercises are focused on practical topics presented in lectures.

The course-unit credit is conditioned by active participation in the seminars, proper preparation of the semester work and fulfilment of the conditions of the control tests.
The exam verifies the knowledge gained during lectures and seminars and is divided into a written theoretical part, part of the computational solution and oral part. The exam considers the work of the student in the exercise. The student must score more than one half of points for the successful completion of the test.

Exercises are compulsory, the form of replacing the missed lessons is solved individually with the exercise trainer or with the course guarantor.
Lectures are optional.

The form of replacement of missed classes is solved individually with the subject guarantor.
