Implementation of Finite Element Approximation of Large-Scale Isometric Deformations of Parametrized Surfaceshttps://doi.org/10.60507/FK2/KZHXDFSmoch, ChristophSimon, StefanRumpf, Martinbonndata2024-01-042024-01-04T07:53:18ZThis is an implementation of the finite element approximation of large-scale isometric deformations of parametrized surfaces using the Discrete Kirchhoff Triangle (DKT) Finite Element, together with a point-wise nonlinear isometry constraint. The solution of this nonlinear problem is obtained by Newton's method from the IPOPT library.Mathematical SciencesFinite Element Approximation of Large-Scale Isometric Deformations of Parametrized Surfaces.
