CFD Solver Developer (M‑Star) (m/w/d), Lyon

By bridging the gap between the physical and digital worlds, we help to accelerate digitalisation and sustainability: so that our customers around the world can become more competitive, resilient and sustainable.

Tasks

• Developing M-Star’s fluid dynamics solver including maintenance, feature addition, algorithm implementation, and validation.
• Translating academic research in numerical methods into a high-performance, easy-to-use software product.
• Modeling a wide-range of physics including fluid dynamics, multiphase flows, advectiondiffusion, particle mechanics, and heat transfer.
• Implementing meshing algorithms and data structures for GPU architectures in a distributed memory environment.
• Working with support engineers and users to tailor software to current needs.
• Performing validation studies and presenting results at conferences.

Profile

• Background in numerical methods for transport physics (fluid dynamics, advection diffusion, particle mechanics, or heat transfer).
• Writing high performance physics codes using parallel computing in shared and distributed memory systems.
• Expertise with Lattice Boltzmann Methods (LBM) for fluid simulation.
• Knowledge of the Discrete Element Method (DEM) for particle mechanics.
• Specialization in numerical methods for multiphase modeling of liquid-liquid and gas-liquid systems.
• Algorithms for computational geometry including structured/unstructured meshing, 3D search, and mesh refinement.
• Detailed understanding of GPU architectures and CUDA toolkit.
• MPI programming for multi-GPU code development.
• Experience working on a large multiphysics solver.
