Researchers have developed a novel method called Spectral-like Neural Discretisation (SpeND) to create mesh-free numerical operators for physics simulations. This technique uses a neural network to learn stencil weights, conditioned on local node geometry, to better approximate spectral operators. A key feature is a projection layer that ensures polynomial consistency by construction, eliminating the need for reference solutions and making the training physics-agnostic. Modal analysis indicates that SpeND operators exhibit superior accuracy over a wider wavenumber band compared to traditional methods like LABFM or finite differences on structured grids, while maintaining fourth-order convergence.
