Researchers have developed a novel Green-Integral (GI) neural solver designed to more efficiently simulate the acoustic Helmholtz equation, particularly in complex heterogeneous media. This new method departs from traditional physics-informed neural networks (PINNs) by utilizing an integral representation to enforce wave physics, which bypasses the need for computationally expensive pointwise PDE residual minimization and artificial boundary layers. The GI solver demonstrates a significant reduction in computational cost, achieving over a tenfold decrease compared to standard PINNs, and offers improved accuracy through a hybrid GI+PDE loss function for regions with strong scattering.
