Field: Calculation
The training courses that will be organised in this area will enable the acquisition of skills with regard to IT tools used within companies in the aeronautics and space sector.
These include training on the following tools:
- Catia V5 and V6 ;
- PLM 2.0 Environment ;
- ANSYS ;
- SAMCEF ;
- PATRAN – NASTRAN ;
- Software products concerning the field of fluid mechanics, aerodynamics, aeroacoustics, aerothermics,…

OBJECTIVES
To refine the knowledge of the behaviour of structures, the current tendency is to take more and more into account non-linear geometric and material effects but also the influence of imperfections or other local effects. The aim of the course is to give an overview of the possibilities of MECANO by drawing the user’s attention to the many pitfalls of the transition from linear to non-linear analysis.
