Idealisation of the solved problem geometry. Simulation and digitalisation of the solved object and the groups of objects. 6. Data compatibility of the SW products used in CAE technologies. Neutral data representations of the CAE models. 7. Choice of the types dimensions and number of elements. Creation and ways of the FEM meshes generation. Topology of the FE model of the analysed objects. 8. Computer processing in FEM. Calculation of the elementary results. Interpretation and discussion of the results. Modification of the calculation model and calculation repetition targeting optimisation of the object according to the pre-selected criteria. 9. Review of the FEM SW products. Possibilities of the result presentation. 10. Example solutions of the selected types of tasks and solutions of the problems of mechanics of the continuum. 11. Discussion of the connections between the stress and deformation analyses of the machine parts performed by means of the methods of technical elasticity, of the known analytical methods, of the methods of the stress and strain experimental analysis and FEM. 12. Importance of the methods of the modal, harmonic and transient analyses. 13. Possibilities and approaches to the simulations of the dynamical response of both individual objects and their groups so called multi-body systems. The technology complexity of so-called Virtual Prototyping, or Virtual Product Development, respectively. 14. Possibilities of solving of multi-physical so called mixed problems of continuum (e.g. thermally structural analyses, piezoelectromechanical analyses, electromagnetic analyses, interaction of the solid and non-solid, so-called fluid continuum etc.) Practice: 1-14. Completion theoretic lessons fit instances that the prove by evidence methodists setting professional software technology.

Learning outcomes
|
The purpose of this course is the introduction to the numerical modelling of engineering processes. There will be summarized theoretical and practical results refered to sequentical steps of the proposal and assembling of the numerical model and its setting up for the particullar application.
Understanding and ability to apply numerical methods in solving the topics within the frame of their further education (diploma project) and in their professional work at various positions (designer, project manager, quality expert etc.).
