Although Regge finite element functions are not continuous, useful generalizations of nonlinear derivatives like the curvature, can be defined using them. This paper is devoted to studying the convergence of the finite element lifting of a generalize

Purpose This paper aims to consider a multiscale electromagnetic wave problem for a housing with a ventilation grill. Using the standard finite element method to discretise the apertures leads to an unduly large number of unknowns. An efficient appro

We compare several lowest-order finite element approximations to the problem of elastodynamics of thin-walled structures by means of dispersion analysis, which relates the parameter frequency-times-thickness ( f d ) and the wave speed. We restrict to

We present a novel numerical scheme to approximate the solution map s ↦ u(s) := 𝓛–s f to fractional PDEs involving elliptic operators. Reinterpreting 𝓛–s as an interpolation operator allows us to write u(s) as an integral including soluti

The present work is concerned with the issue of spurious coupling effects that are pervasive in fully coupled magneto-mechanical finite element simulations involving very soft non-magnetic or air-like media. We first address the characterization of t

The multiscale finite element method (MSFEM) is a valuable tool to solve the eddy current problem in laminated materials consisting of many iron sheets, which would be prohibitively expensive to resolve in a finite element mesh. It allows using a coa

An efficient approach to simulate the multiple scales, occurring in metascreens, is introduced. Due to the fine discretization around apertures, the standard finite element (FE) method leads to a large number of unknowns. Therefore, the generalized F

One approach for the simulation of metamaterials is to extend an associated continuum theory concerning its kinematic equations, and the relaxed micromorphic continuum represents such a model. It incorporates the Curl of the nonsymmetric microdistort
