code_aster: non-linearity, fatigue and multiphysics couplings
Develop your expertise in code_aster to solve advanced industrial problems, by carrying out non-linear calculations, fatigue analyses and multiphysics couplings.

Course summary
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 or how to structure your first simulations.
- You run mechanical simulations that fail to converge or produce inconsistent results: poorly defined boundary conditions, incorrect material properties, contact or non-linearity issues… and you spend hours trying to figure out what's going wrong.
- You struggle to interpret .mess files and solver messages: has the simulation actually converged? Are the Newton iterations acceptable? Are the results physically consistent?
- You want to go beyond tutorials and fully master code_aster to adapt it to your industrial use cases: automating simulations, chaining multiple analyses, running parametric studies, or integrating the solver into a broader simulation workflow.
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 installation to post-processing: the complete workflow
You learn to operate and master the tools (Salomé, code_aster 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 engineers and PhDs use code_aster 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 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
Basic proficiency in code_aster. Good general knowledge of continuum mechanics and numerical solution methods. Basic knowledge of non-linear analysis.
