Summary

• What is new: Introducing Transolver, a novel method that employs Physics-Attention to adaptively split the domain of PDEs into learnable slices for better modeling of physical states.
• Why this is important: Difficulty in capturing intricate physical correlations in PDEs due to discretized, complex geometries with large-scale meshes.
• What the research proposes: Transolver uses Physics-Attention to dynamically group mesh points into slices based on similar physical states, enabling efficient and accurate capture of physical correlations.
• Results: Transolver demonstrates a 22% relative gain over state-of-the-art models across six benchmarks and shows significant improvement in industrial simulations, such as car and airfoil designs.
