CFD Solver Developer (Computational Physics)

About the role

We are looking for a Computational Physicist to join our M-Star team. M-Star is a specialized team developing world-class CFD software for multiple industries including Life Sciences, Chemical Material, and Industrial. The role involves contributing directly to the development of the fluid dynamics solver, translating academic research into practical software, and implementing multiphysics models.

Responsibilities

• 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, advection-diffusion, 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.

Requirements

• 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.
• Experience with GPU architectures and CUDA toolkit.
• Experience with MPI programming for multi-GPU code development.
• Experience working on a large multiphysics solver.
