Modelling and Simulation in Mechanics

Head: Grégory LEGRAIN


Numerical simulation has become a fundamental tool across all industrial sectors. This approach is now considered as the third pillar of science (alongside the two historic pillars of theory and observation).

Since any computer-based approach will always provide a result - be it valid or not - an understanding of the limitations is indispensable. Numerical methods and modelling skills are essential in this respect. First of all, it is necessary to conceptualise the physical aspect of the problem in question: several different levels of simplification (models) will be possible according to the objectives of the study. Furthermore, the numerical algorithms used to solve the equations will need to be adapted.  In short, it is crucial to a) solve the right equations, and b) solve them correctly. Finally, numerical results have to be interpreted by engineers in order to propose model improvements where necessary. Dialogue between testing and calculation is thus of paramount importance.

Sectors of activity and employment prospects

This specialisation prepares students for a broad range of careers: research and development engineer (usually post PhD), structural engineer, engineering consultant, etc. The courses draw on the different facets of these positions: physical modelling, numerical methods, dialogue with testing. Whilst the specialisation directs students mainly towards specialist positions, career progression towards management posts is also accessible.

Previous students of this specialisation work today in diverse sectors of activity: automotive, naval and offshore, aeronautics, rail, energy, construction, bio-mechanics etc.
