Our lab is pleased to announce that our paper, “An efficient multiscale coupling method for simulations of reactor-scale chemical vapor deposition with microstructural features,” has been published in Advances in Engineering Software [link], with contributions from collaborators at POSTECH and Samsung Electronics. This work presents a high-fidelity multiscale CVD modeling framework that couples a full 3D reactor-scale model with a parameterized feature-scale model through an effective reaction-rate formulation. The proposed method significantly reduces computational cost while maintaining high accuracy, enabling practical large-scale CVD simulations.

Our lab is pleased to announce that the paper “Towards a widespread usage of computational fluid dynamics simulations for automated virtual nasal surgery planning” has been published in Future Generation Computer Systems [link]. This work was led by Dr. Mario Rüttgers, with contributions from collaborators at RWTH Aachen, University of Latvia, Kobe University, RIKEN, and Forschungszentrum Jülich. he study introduces an efficient hybrid lattice-Boltzmann and level-set–based CFD framework that significantly reduces computational cost for virtual nasal surgery planning. The method enables fast prediction of pressure loss, airflow balance, and tissue-removal implications, making CFD-based surgical planning far more accessible for clinical environments. his publication marks an important advancement toward widespread, automated, and affordable CFD-assisted surgical decision-making.

We developed a neural network-based thermal model for Korea’s first lunar orbiter, Danuri, enabling real-time temperature prediction from the ground. By combining active and transfer learning, our model achieves high accuracy with drastically reduced computation time—serving as a digital twin for spacecraft thermal monitoring. This joint work with POSTECH and KARI pushes the frontier of AI-driven virtual metrology for space missions. Check our work at : [link]

New publication in Physics of Fluids (POF)! We developed a CNN that predicts drag forces on rough surfaces using only topography data through an international collaboration (INHA, KTH (Sweden), and KIT (Germany)). Our model reveals key patterns linked to drag, offering insights into fluid dynamics without needing complex parameters. Check out how we're advancing data-driven drag prediction (Link)!
