Researchers have developed a novel method for coupling Physics-Informed Neural Networks (PINNs) with Finite Element Methods (FEM) by framing the interaction as a Steklov-Poincaré operator. This approach addresses limitations in existing empirical PINN-FEM schemes by providing a theoretical foundation for their integration. The new framework includes a closed-form interface impedance and a contraction theorem specific to PINNs, demonstrating improved accuracy and stability in fluid-structure interaction problems, particularly those involving contact and topology changes.
