Course summary

See the course page

Do you recognize yourself?

  • You want to switch to open-source code for better technological control and a cost advantage, but you don't know where to start.
  • You waste time re-running calculations that fail: a poorly defined boundary condition, a mesh that is too coarse, a forgotten density–temperature coupling — and you only find out after hours of simulation.
  • You lack a method to read and interpret code_saturne log files: has the calculation actually converged? Are the residuals acceptable? Impossible to decide without solid benchmarks.
  • You don't know how to validate your results. Your simulations run, but without comparison against experimental data or reference cases, you are moving forward without a safety net.

Why our training in particular?

Theory revisited, immediate practice

Two days of hands-on practice backed by a review of theoretical fundamentals. Each practical exercise is more demanding than the previous one: you progress in concrete steps, from discovery to industrial-level work — not through slides.

From geometry to post-processing: the complete workflow

You learn to operate and master the tools (Salomé, code_saturne and Paraview) together, as in your day-to-day work. Not just the solver: the entire simulation chain.

Practitioner trainers, in front of you

Our CFD engineers and PhDs use code_saturne daily on industrial projects at Simvia. In person, they share with you live the best practices, the pitfalls to avoid and the troubleshooting tips you won't find in any documentation.

Close-knit supervision

1 trainer for a maximum of 8 trainees during practical work. When you get stuck, an expert is right beside you.

A network, not just a training course

The inter-company format brings together engineers from different sectors and backgrounds around the same CFD challenges. You exchange feedback, compare approaches and leave with a network of peers who share your technical day-to-day.

Audience

  • Corporate: engineers and technicians with a basic understanding of the physical and digital aspects covered by the course.
  • Academic: researchers, PhD students and students at higher education and research institutions.

Prerequisites

Proficiency in code_saturne for simple analyses. In-depth knowledge of fluid mechanics. Solid foundation in CFD along with knowledge of thermo-hydraulics.

Florian Hermet

Holding a PhD and teaching in fluid mechanics, I practice CFD with one simple conviction: a simulation is only useful if you truly understand what you are doing. Every mesh, every model, every convergence criterion directly influences the results. Between advanced research and industrial projects, I have learned to never take a simulation for granted and to always challenge it against the physics and common sense. In my training courses on code_saturne, I share a pragmatic approach: structuring your methodology, avoiding classic pitfalls, and producing reliable and defensible simulations. My goal is simple: to make you autonomous and confident in your simulations.
