Researchers have developed a new adaptive sampling strategy for physics-informed neural networks (PINNs) to improve their generalization capabilities in metal additive manufacturing. This method, detailed in a recent arXiv paper, uses a conditional Flow Matching model to learn distributions of high-residual areas, which are then combined with domain-informed sampling to generate more effective collocation points. Experiments show this approach significantly reduces error compared to traditional static sampling methods, offering better thermal modeling for metal additive manufacturing processes. AI
