Job Description

In many industrial and research applications, tracking millions of particles within a fluid flow is essential, but current CPU-based methods are too slow. This project offers an exciting opportunity to break that bottleneck by building a state-of-the-art solver that leverages the massive power of modern GPUs to accelerate simulations by orders of magnitude. Join us in developing a cutting-edge tool that integrates directly with the industry-standard Computational Fluid Dynamics (CFD) software OpenFOAM, and make a significant impact on what's possible in computational science.

• As a part of your Master thesis, you will conduct a literature review on state-of-the-art methods for Lagrangian Particle Tracking, GPU computing in CFD and particle-wall interaction.
• You will develop a high-performance particle tracking solver using Python and the NVIDIA Warp framework to run on the GPU.
• In addition, you will implement a method for collision detection with complex 3D geometries and create a pre-processing pipeline to prepare simulation data (e.g., flow fields and meshes) from OpenFOAM for the GPU.
• Furthermore, you will integrate the new solver into a standard OpenFOAM workflow, establishing a seamless data exchange.
• Last but not least, you will validate and benchmark your solver's performance against OpenFOAM's native tools, quantifying the massive speedup.

Qualifications

• Education: Master studies in the field of Engineering, Physics or comparable
• Experience and Knowledge: profound knowledge of and experience in numerical simulation methods, as well as a solid understanding of continuum mechanics; very good programming skills in Python; initial experience with OpenFOAM, NVIDIA Warp and ParaView is desirable; ideally, initial experience with Git and working on HPC clusters
• Personality and Working Practice: you are able to proactively develop new ideas, find solutions independently and complete tasks efficiently, demonstrating a high degree of self-motivation
• Work Routine: partially mobile working possible, ideally with 3 - 4 office days per week
• Languages: business fluent in English and good in German
