Course detail
Finite Element Method - Advanced Analyses
FSI-ZAW Acad. year: 2021/2022 Summer semester
Solution of real engineering problems using FEM. Calculation of linear and non-linear analysis of beam structures, stress-strain analysis of machine parts, contact analysis, modal analysis, heat transfer, basics of CFD analysis and topological optimalization. Emphasis is placed also on the analysis and interpretation of results, which is an inseparable part of FEM analyses.

Learning outcomes of the course unit
Students will significantly extend their knowledge in the field of FEM. They will learn to work in ANSYS Workbench environment. Due to analysis of real components and structures, they will learn self-reliance in the FEM calculations.
Prerequisites
– Knowledge of mechanics, dynamics, strength of materials, CAD modelling and material sciences at the level of bachelor's study of mechanical engineering.
Planned learning activities and teaching methods
Lectures, seminars, self-study.
Assesment methods and criteria linked to learning outcomes
Course credit is awarded on the following conditions:
- active taking part in the lectures (max. 10 points),
- solving of assigned tasks and presentation of results (max. 30 points),
- at least it is necessary to get 20 points.
Exam is awarded on the following conditions:
- practical part: methodically correct solution of assigned task (max. 40 points),
- oral exam (max. 20 points),
- together one can obtain up to 100 points, final grade is determined in accordance with ECTS grading scale.
Aims
Aim of the course is to extend students’ knowledge in area of finite element methods (FEM), while practicing ANSYS Workbench software. Emphasis is placed on acquiring comprehensive knowledge about FEM analyses through practical exercises focused on: computational model creation; correct solver settings, solution and interpretation of the results.
Specification of controlled education, way of implementation and compensation for absences
Attendance at practicals is obligatory and checked by the lecturer. One excused absence can be tolerated without compensation. In case of longer absence, compensation of missed lessons depends on the instructions of course supervisor.
