ElVis: A System of the Accurate and Interactive Visualization of High-Order Finite Element Solutions

This paper presents the Element Visualizer (ElVis), a new, open-source scientific visualization system for use with highorder finite element solutions to PDEs in three dimensions. This system is designed to minimize visualization errors of these types of fields by querying the underlying finite element basis functions (e.g., high-order polynomials) directly, leading to pixel-exact representatio...

Efficient Finite Element Assembly of High Order Whitney Forms

This paper presents an efficient method for the finite element assembly of high order Whitney elements. We start by reviewing the classical assembly technique and by highlighting the most time consuming part. Then, we show how this classical approach can be reformulated into a computationally efficient matrix-matrix product. We also address the global orientation problem of the vector valued ba...

Efficient Parallel Preconditioners for High-Order Finite Element Discretizations of H(grad) and H(curl) Problems

In this paper, we study preconditioning techniques for both H(grad) and H(curl) problems. For an H(grad) elliptic problem discretized by high-order finite elements with a hierachical basis of k-th order, we design and analyse an parallel AMG preconditioner based on a two-level method and a block Gauss–Seidel smoothing technique. For an H(curl) elliptic problem discretized by high-order edge fin...

High-Order Accurate Discontinuous Finite Element Solution of the 2D Euler Equations

This paper deals with a high-order accurate discontinuous finite element method for the numerical solution of the Euler equations. The method combines two key ideas which are at the basis of the finite volume and of the finite element method, the physics of wave propagation being accounted for by means of Riemann problems and accuracy being obtained by means of high-order polynomial approximati...

High Order Extended Finite Element Method for Cracked Domains

Computer simulation of fracture processes remains a challenge for many industrial modelling problems. In a classical finite element method, the non-smooth displacement near the crack tip is captured by refining the mesh locally. The number of degrees of freedom may drastically increase, especially in three dimensional applications. Moreover, the incremental computation of a crack growth needs f...
