Higher-order finite elements for embedded simulation

ACM Transactions on Graphics, 2020
As demands for high-fidelity physics-based animations increase, the need for accurate methods for simulating deformable solids grows. While higherorder finite elements are commonplace in engineering due to their superior approximation properties for many problems, they have gained little traction in the computer graphics community.

On Higher Order Pyramidal Finite Elements

Advances in Applied Mathematics and Mechanics, 2011
In this paper we first prove a theorem on the nonexistence of pyramidal polynomial basis functions. Then we present a new symmetric composite pyrami- dal finite element which yields a better convergence than the nonsymmetric one. It has fourteen degrees of freedom and its basis functions are incomplete piece- wise triquadratic polynomials. The space of

Higher-Order Finite Element for Sandwich Plates

AIAA Journal, 1998
A finite element model for the analysis of sandwich plates with laminated composites face-sheets is developed. In the model, the face-sheets are represented as ReissnerMindlin plates and therefore include shear deformation effects. The core is modelled as a three-dimensional continuum in which the through-thickness representation of the displacement ...

Electromagnetic Scattering by Isoparametric Elements of Higher Order

Computational Methods in Applied Mathematics, 2014
Abstract. A boundary element method with higher order isoparametric elements allows for the simulation of scattering problems given by the electric field integral equation. This paper describes the implementation and provides striking numerical evidence of the higher order convergence rates for the approximation of the electric surface ...

Methods and framework for visualizing higher-order finite elements

IEEE Transactions on Visualization and Computer Graphics, 2006
The finite element method is an important, widely used numerical technique for solving partial differential equations. This technique utilizes basis functions for approximating the geometry and the variation of the solution field over finite regions, or elements, of the domain.

Asteroid Mean Elements: Higher Order and Iterative Theories

Celestial Mechanics and Dynamical Astronomy, 1998
The authors present an accurate and reliable algorithm to compute mean elements of asteroids. A satisfactory accurracy is obtained much closer to the strongest mean motion resonances. The fixed-point-based algorithm is iterative, with the first-order theory as an iteration step.
