Solving elliptic eigenproblems with adaptive multimesh hp-FEM [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2021
This paper proposes a novel adaptive higher-order nite element (hp-FEM) method for solving elliptic eigenvalue problems, where n eigenpairs are calculated simultaneously, but on individual higher-order nite element meshes. The meshes are automatically hp-

Wavenumber-explicit convergence of the hp-FEM for the full-space heterogeneous Helmholtz equation with smooth coefficients [PDF]

open access: yesComputers and Mathematics with Applications, 2020
A convergence theory for the $hp$-FEM applied to a variety of constant-coefficient Helmholtz problems was pioneered in the papers [Melenk-Sauter, 2010], [Melenk-Sauter, 2011], [Esterhazy-Melenk, 2012], [Melenk-Parsania-Sauter, 2013].

FINITE ELEMENT ANALYSIS OF A SINGLE-PHASE INDUCTION MOTOR WITH NON-UNIFORM STATOR SLOTS BASED ON MAGNET SOFTWARE AND AUTOCAD

open access: yesJournal of Engineering and Sustainable Development, 2022
The current study uses the finite element technique to investigate a single-phase induction motor with non-uniform stator slots. A 0.5 hp, four poles, 36 stator slots, and 48 rotor slots have non-uniform stator slots were analyzed based on magnet Finite

hp-FEM for the spectral fractional Laplacian in polygons

open access: yes, 2023
The numerical treatment of fractional differential operators is challenging due to their non-local nature. Additional numerical challenges arise in particular in the case of bounded domains from strong singularities of the solution at the boundary.

Parallel self-adaptive hp finite element method with shared data structure [PDF]

open access: yesComputer Methods in Materials Science, 2011
In this paper we present a new parallel algorithm of the self-adaptive hp Finite Element Method (hp-FEM) with shared data structures. The algorithm generates in a fully automatic mode (without any user interaction) a sequence of meshes delivering ...
