This approach lets us skip time-intensive simulations of complex systems, which could become prohibitively expensive for larger, real-world applications.

The key insight: our model learns by observing molecular interactions in simple uniform bulk systems. Once it grasps these patterns, it can predict behavior in complex environments like poresβ€”despite never encountering non-uniform conditions during training.

Scientists traditionally rely on computer simulations to understand molecular-level behavior of liquids and gases. However, these simulations can be incredibly time-consuming. ⏳
