Course detail
Finite Element Method - Advanced Analyses
FSI-ZAW Acad. year: 2022/2023 Summer semester
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.
