Parametric Neural r-Adaptivity for Isogeometric Analysis via Residual Minimization

Elías Caru, David Pardo, Judit Muñoz-Matute

We propose an r-adaptive neural algorithm for Isogeometric Analysis (IGA) based on residual minimization. The boundary-value problem is solved using a standard conforming Galerkin…
