MATHICSE Technical Report : Isogeometric Analysis on V-reps: first results [PDF]
Inspired by the introduction of Volumetric Modeling via volumetric representations (V-reps) by Massarwi and Elber in 2016, in this paper we present a novel approach for the construction of isogeometric numerical methods for elliptic PDEs on trimmed ...

Advanced Science, Volume 13, Issue 60, 28 October 2026.A latent diffusion‐based framework is proposed for designing functionally graded metamaterials with perfect connectivity. By integrating vector‐quantized latent representations with mechanistic guidance, the framework enables accurate inverse design toward target elastic properties.

Planar Parametrization in Isogeometric Analysis [PDF]
, 2014 Before isogeometric analysis can be applied to solving a partial differential equation posed over some physical domain, one needs to construct a valid parametrization of the geometry. The accuracy of the analysis is affected by the quality of the parametrization.

An isogeometric Reissner–Mindlin shell element based on mixed grid
Advances in Mechanical Engineering, 2018 We propose in this article a new isogeometric Reissner–Mindlin degenerated shell element for linear analysis. It is based on the mixed use of non-uniform rational basis spline and Lagrange basis functions in the same domain.

Isogeometric analysis: vibration analysis, Fourier and wavelet spectra [PDF]
Journal of Theoretical and Applied Vibration and Acoustics, 2017 This paper presents the Fourier and wavelet characterization of vibration problem. To determine the natural frequencies, modal damping and mass participation factors of bars, a rod element is established by means ofisogeometric formulation.

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT Vector extrapolation techniques can be highly effective when used to accelerate the convergence of fixed‐point iterative methods, such as the Picard method. In this study, we investigate the numerical solution of nonlinear problems. Specifically, we address the nonlinear eigenvalue Bratu problem and the Monge–Ampère equation using a multigrid ...

Isogeometric Analysis of FGM Plates
Materials Today: Proceedings, 2018 Abstract This work presents an isogeometric formulation for the geometrically nonlinear analysis of functionally graded material (FGM) plates. FGM plates are made of a mixture of two components (ceramic and metal) whose volume fractions vary smoothly along the thickness.
