Structural mechanics

Our engineers’ mechanical design and calculation skills cover the use of CAD tools such as Catia V5, SolidWorks and AutoCad, together with simulation tools such as Ansys, Abaqus and Nastran.

These advanced skills allow us to provide our various clients with the following:

  • The design and dimensioning of mechanical structures and systems,
  • The study of complex phenomena such as fracture and vibratory mechanics.

In order to manage the designing of a full system, we prefer to use an organisation in project mode which brings together all of the phases involved in developing the systems:

  • Technical feasibility analysis (functional analysis, AMDEC, etc.),
  • Pre-dimensioning,
  • Overall design,
  • Detailed design,
  • Justification by digital modelling.

Fluid Mechanics

Our engineers’ skills in both calculation (CFD) and the complete building of systems mean that they are fully conversant with CFD applications such as Fluent, Star CD, SolidWorks Flow Simulation and EcosimPRO

These skills allow us to operate in the following areas:

  • Internal and external aerodynamic calculations
  • Shape optimisation
  • Pressure loss calculations

The complete building of systems covers all the phases involved in the development of fluid systems:

  • Technical feasibility analysis
  • Pre-dimensioning
  • Detailed design
  • Test study
  • Final validation

The sectors in which we operate are the Aeronautical, Defence, Nuclear and Oil / Petrochemical etc. industries.

Areas of application

  1. Nuclear industry
  2. Wind power
  3. Oil and Gas industry
  4. Space industry
  5. Hydraulics
  6. Aeronautical industry
  7. Motor industry
  8. Defence industry
