Implementation of higher-order vertical finite elements in ISSM v4.13 for improved ice sheet flow modeling over paleoclimate timescales [PDF]
Geoscientific Model Development, 2018 Paleoclimate proxies are being used in conjunction with ice sheet modeling experiments to determine how the Greenland ice sheet responded to past changes, particularly during the last deglaciation.

Higher Order Cut Finite Elements for the Wave Equation [PDF]
Journal of Scientific Computing, 2019 The scalar wave equation is solved using higher order immersed finite elements. We demonstrate that higher order convergence can be obtained. Small cuts with the background mesh are stabilized by adding penalty terms to the weak formulation. This ensures that the condition numbers of the mass and stiffness matrix are independent of how the boundary ...

A second order cell method for Poisson's equation [PDF]
, 2010 The Cell Method, similar to the Finite Integration Technique, is a well-established numerical method for the solution of field problems, however an often raised criticism is that it is limited to constant fields within elements.

Enriched Finite Element Method Based on Interpolation Covers for Structural Dynamics Analysis
Machines, 2023 This work proposes a novel enriched finite element method (E-FEM) for structural dynamics analysis. We developed the enriched 3-node triangular and 4-node tetrahedral displacement-based elements (T-elements).

Duality of Complex Systems Built from Higher-Order Elements
Complexity, 2018 The duality of nonlinear systems built from higher-order two-terminal Chua’s elements and independent voltage and current sources is analyzed. Two different approaches are now being generalized for circuits with higher-order elements: the classical ...

Fractional generalization of memristor and higher order elements [PDF]
Communications in Nonlinear Science and Numerical Simulation, 2013 Abstract Fractional calculus generalizes integer order derivatives and integrals. Memristor systems generalize the notion of electrical elements. Both concepts were shown to model important classes of phenomena. This paper goes a step further by embedding both tools in a generalization considering complex-order objects.

Large deflection analysis of frames by elements containing higher-order terms
Vietnam Journal of Mechanics, 2003 In this paper, the beam elements using higher-order terms for large deflection analysis of elastic frames are discussed. The elements based on the co-rotational method are derived using the strain energy and effective strains.
