FAQ about the Numerical Simulation Engineer

What is a numerical simulation engineer?

A numerical simulation engineer is a specialist who uses mathematical models and computational software to simulate the behaviour of complex physical systems before they are built or tested. They work in fields such as aerospace, automotive, energy, construction, and scientific research, where simulation reduces costs and accelerates product development.

What is the salary of a numerical simulation engineer in France?

In France, a junior numerical simulation engineer typically earns between €40,000 and €60,000 gross per year. A mid-level profile ranges from €60,000 to €80,000, and a senior can reach €80,000 to over €100,000. Aerospace, nuclear, and automotive sectors offer the highest salaries.

What is the difference between a numerical simulation engineer and a computational engineer?

The two terms often describe the same role. "Computational engineer" is the term historically used in industry (aeronautics, automotive) for profiles specialising in numerical methods and finite elements. "Numerical simulation engineer" is a broader term that also covers process simulation, computational fluid dynamics (CFD), and system simulation. In practice, the skills are very similar.

What skills do you need to become a numerical simulation engineer?

You need to master simulation tools (ANSYS, COMSOL, MATLAB, Simulink, Abaqus), numerical analysis and mathematical methods (finite elements, finite volumes, finite differences), and have a solid understanding of the physical phenomena being simulated (mechanics, thermodynamics, fluids). Programming skills (Python, Fortran, C++) to script and automate simulations are also highly valued.

What are the responsibilities of a numerical simulation engineer?

Their responsibilities include analysing simulation needs, building mathematical and computational models, running simulations to test scenarios, analysing results and formulating recommendations, optimising designs based on findings, and collaborating with design teams and researchers.

What tools does a numerical simulation engineer use?

They use finite element simulation software (ANSYS Mechanical, Abaqus, NASTRAN) and fluid dynamics tools (ANSYS Fluent, OpenFOAM, STAR-CCM+), system modelling environments (MATLAB/Simulink, Modelica), and result visualisation tools (ParaView, Tecplot). Python or scripting skills to automate simulation pipelines are increasingly in demand.

What training is needed to become a numerical simulation engineer?

A Master's-level degree in mechanical engineering, aeronautical engineering, applied physics, or applied mathematics with a specialisation in numerical computation or computational mechanics is typically required. Engineering schools with specialised simulation Master's programmes (ISAE, Centrale Paris, École Polytechnique, INSA…) produce the most sought-after profiles by large industrials.

How does a numerical simulation engineer's career evolve?

A numerical simulation engineer can progress to simulation project manager, simulation architect, head of numerical methods, or advanced simulation researcher. Some specialise in niche areas such as crash simulation, high-performance CFD, or multi-physics simulation. Others move into consulting or join simulation software vendors.
