Credits will be awarded upon successful completion of a technical report on the solution of a specific computational problem. The report must contain the description of the problem, overview of the employed methods and solution steps (including the set boundary conditions), as well as the summary and analysis of results in both graphical and alphanumeric form. The necessary condition for awarding credits is regular participation in the seminars, i.e., in at least two thirds of them (9 out of the total 13).

The objective of the course is to provide hands-on experience in solution of various types of problems that are typical of CFD and its industrial applications. The students will get acquainted with the complete process of setting up and solving fluid flow problems using commercial software ANSYS Fluent. They will learn about various methods and ways to construct the geometry, create computational grids, define boundary conditions, and choose appropriate models for specific CFD problems. They will gain experience in computational modelling of various types of problems encountered in engineering practice, including the overlap with multiphysics problems.
