TensorGalerkin framework accelerates PDE solving and learning

Researchers have developed a new algorithmic framework called TensorGalerkin for solving, optimizing, and learning partial differential equations (PDEs) with variational structures. This framework utilizes an efficient Galerkin discretization and a GPU-compliant TensorGalerkin method for assembling linear systems. The TensorGalerkin approach optimizes element-wise operations within PyTorch's autograd, enabling a constant-node assembly graph regardless of mesh size. Benchmarks across various PDE types demonstrate significant computational efficiency and accuracy gains compared to existing methods in numerical solving, constrained optimization, and physics-informed operator learning.
