A meshfree exterior calculus for generalizable and data-efficient learning of physics from point clouds

Researchers introduce MEEC (meshfree exterior calculus), a novel framework for learning physics directly from point clouds without requiring mesh generation. MEEC-Net, built on this approach, demonstrates 1-2 orders of magnitude better generalization across different geometries, resolutions, and physical parameters compared to existing neural operator methods, achieving this with minimal training data.

RigidFormer: Learning Rigid Dynamics using Transformers

RigidFormer is a Transformer-based neural network that learns rigid-body dynamics simulation from mesh-free point cloud inputs, addressing computational bottlenecks in existing mesh-dependent methods. The model uses object-level reasoning with anchor-based attention mechanisms and enforces physical rigidity constraints through differentiable Kabsch alignment, demonstrating superior performance and generalization across benchmarks.
