An -adaptive finite element method using neural networks for parametric self-adjoint elliptic problem
Danilo Aballay, Federico Fuentes, Vicente Iligaray +5
This work proposes an -adaptive finite element method (FEM) using neural networks (NNs). The method employs the Ritz energy functional as the loss function, currently limiting i…

Reflectionless discrete perfectly matched layers for higher-order finite difference schemes
Vicente A. Hojas, Carlos Pérez-Arancibia, Manuel A. Sánchez
This paper introduces discrete-holomorphic Perfectly Matched Layers (PMLs) specifically designed for high-order finite difference (FD) discretizations of the scalar wave equation.…

Quasi-interpolators with application to postprocessing in finite element methods
Thomas Führer, Manuel A. Sánchez
We design quasi-interpolation operators based on piecewise polynomial weight functions of degree less than or equal to that map into the space of continuous piecewise polynomia…
