Internship - CFD Hydrodynamics Engineer (F/M)

Topic: Implicit wave relaxation in the foamStar CFD solver

Join a global leader in maritime classification and certification.

Your career is about more than building a CV – it's a chance to LeaveYourMark.

Joining Bureau Veritas Marine & Offshore means becoming part of a world-leading organization in maritime classification and certification.

For nearly two centuries, we have been supporting innovation and transformation across the maritime sector, ensuring the safety, performance, and sustainability of ships and offshore infrastructures worldwide.

Our mission? To contribute to a safer and more sustainable maritime world, by providing our technical expertise and commitment to our clients and partners.

Passionate about numerical simulation and curious to explore the maritime world?

Join the Hydrodynamics and Metocean team of the Marine & Offshore Research department, based in Saint-Herblain (Nantes area, France). As part of the Centrale Nantes – Bureau Veritas Chair in Hydrodynamics and Marine Structures, the team develops foamStar, an OpenFOAM-based CFD solver that simulates wave-structure interactions for naval and offshore applications.

Context: in foamStar, waves are currently generated through explicit relaxation zones, where velocity and water fraction fields are forced at each iteration. Your goal? Implement a new relaxation method for the incident wave field based on an implicit formulation, then validate it on test cases specific to our applications.

Your main missions

Within the Research team, you will:

• Implement a new implicit relaxation method for the incident wave field in foamStar;
• Run a validation campaign covering pure wave propagation and wave-structure interaction cases;
• Analyze the results obtained with the new tool;
• Apply best practices in scientific computing and software development (Slurm, Git, testing, etc.).

Depending on progress, you may also investigate the relevance of focused waves for computing added resistance in waves.

Your strengths to succeed

• Master's student in engineering or equivalent, ideally specializing in fluid mechanics or ocean engineering;
• Interest in programming and developing computational codes;
• Rigor, curiosity, and autonomy;
• Good command of English, both written and spoken, in an international working environment.

Preferred qualifications

• Hands-on experience with Python or C++ in a Linux environment
• Initial experience with OpenFOAM or another CFD code

Allowance and benefits

• Location: Saint-Herblain (Nantes area)
• Allowance: €1,300 to €1,600 gross / month, depending on level of studies
• 50% reimbursement of your public transport pass
• Works Council (CSE): subsidy for leisure and cultural activities

Why join Bureau Veritas Marine & Offshore?

By joining Bureau Veritas Marine & Offshore, you will be part of:

• An international, ambitious, and open-minded team, driven by a passion for the maritime world;
• A work environment built on trust, collaboration, and talent development;
• A company that values curiosity, initiative, and innovation.

Bureau Veritas is committed to equal opportunity and diversity. We promote gender equality and support the professional integration, access, and retention of people with disabilities.
