Unfitted finite element interpolated neural networks

Wei Li, Alberto F. Martín, Santiago Badia

We present a novel approach that integrates unfitted finite element methods and neural networks to approximate partial differential equations on complex geometries. Easy-to-generat…

Compatible finite element interpolated neural networks

Santiago Badia, Wei Li, Alberto F. Martín

We extend the finite element interpolated neural network (FEINN) framework from partial differential equations (PDEs) with weak solutions in to PDEs with weak solutions in $H…

Adaptive Finite Element Interpolated Neural Networks

Santiago Badia, Wei Li, Alberto F. Martín

The use of neural networks to approximate partial differential equations (PDEs) has gained significant attention in recent years. However, the approximation of PDEs with localised…

Space-time unfitted finite elements on moving explicit geometry representations

Santiago Badia, Pere A. Martorell, Francesc Verdugo

This work proposes a novel variational approximation of partial differential equations on moving geometries determined by explicit boundary representations. The benefits of the pro…

High order unfitted finite element discretizations for explicit boundary representations

Pere A. Martorell, Santiago Badia

When modeling scientific and industrial problems, geometries are typically modeled by explicit boundary representations obtained from computer-aided design software. Unfitted (also…
