Supervisor: doc. Ing. Pavel Maňas, Ph.D.  
Supervising institute: ÚK all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

Students will be able to create multiphysical computational models, perform methodologically correct simulations and complex evaluation of the stress state of complex parts and assemblies, taking into account various nonlinearities.
Learning outcomes and competences:

- Ability to perform simple multiphysics simulations of the stress state of complex components and assemblies in the field of mechanical engineering.
- Ability to comprehensively prepare complex geometries, use advanced methods of mesh creation, specify complex boundary conditions and material properties, model parameterization.
- Deepening the experience with the use of software ANSYS Workbench and ANSYS Discovery, deepening skills in the interpretation of simulation results.
- Deepening the skills needed to work with a modern FEM system, either in the form of stand-alone software or an integrated module in the CAD system.
- Understanding the importance of advanced structural analysis in engineering practice.
Prerequisites:
- Knowledge of mechanics, dynamics, strength of materials, CAD modelling and material sciences at the level of bachelor's study of mechanical engineering.
Course contents:

The course is focused on nonlinear analysis of the stress state of components and assemblies in the field of mechanical engineering. Furthermore, students will get acquainted with the basics of computational fluid mechanics, performing simulations of fast dynamic processes and simulations of additive processes. Emphasis is placed on the methodological creation of a complex computational model, its parameterization, interpretation, verification and validation of simulation results, estimation and evaluation of various effects on the accuracy of results.
The course develops and integrates knowledge from previous studies, creates prerequisites for successful management of complex design projects.
