Simulations in Mechanical Engineering (FSI-ZSK)

Graduates will acquire fundamental competencies in preparing computational models from CAD models, in their proper use, and in evaluating the results obtained from simulations, including the verification and validation of these results. They will understand the significance of modeling and simulation in digital engineering as well as in technical practice.

Graduates will be capable of performing basic linear structural analyses focused on evaluating the stress state of a parts or a simple assembly, analyzing simple cases of fluid flow, and conducting basic analyses of heat transfer within a part or a simple assembly. They will be able to create an appropriate computational model of a real part or a simple assembly and apply relevant boundary conditions. They will be able of assessing simulation result trends across different design variants and making informed decisions regarding further development steps.

They will develop the skills and foundational habits necessary for working with modern CAE systems (such as ANSYS Discovery), either as standalone FEM software or as an integrated module within a CAD system.

Basic knowledge of mechanics (solids and fluids), strenght of materials, CAD modelling, machinery design and material science.

Digital engineering in the field of design processes introduces new possibilities through the development of advanced methods for modeling and simulating mechanical systems, but also new challenges concerning the requirements placed on users of modern CAD/CAE and MBSE systems.

Within the course, students will acquire competencies for solving basic linear structural problems such as strength and thermal analysis of components, modal analysis, basic CFD analysis (fluid flow resistance), and shape optimization of components. Emphasis is placed on the distinction between analytical and numerical approaches, as well as on the interpretation, verification, and validation of the obtained results.

The course integrates knowledge gained from previous undergraduate studies in mechanical engineering and establishes a foundation for successfully completing simpler design projects and bachelor’s theses.

Course credit is awarded on the following conditions:
- active taking part in the lectures (max. 10 points),
