Convergence of Lagrange Finite Element Methods for Maxwell Eigenvalue Problem in 3D

Daniele Boffi, Sining Gong, Johnny Guzmán +1

We prove convergence of the Maxwell eigenvalue problem using quadratic or higher Lagrange finite elements on Worsey-Farin splits in three dimensions. To do this, we construct two F…

Loosely coupled, non-iterative time-splitting scheme based on Robin-Robin coupling: unified analysis for parabolic/parabolic and parabolic/hyperbolic problems

Erik Burman, Rebecca Durst, Miguel Fernández +1

We present a loosely coupled, non-iterative time-splitting scheme based on Robin-Robin coupling conditions. We apply a novel unified analysis for this scheme applied to both a Para…

SPH modeling of natural convection around a heated horizontal cylinder: A comparison with experiments

F. Aragón, J. E. V. Guzmán, L. Di G. Sigalotti +4

An experimental and numerical smoothed particle hydrodynamics (SPH) analysis was performed for the convective flow arising from a horizontal, thin cylindrical heat source enclosed…

A discrete elasticity complex on three-dimensional Alfeld splits

Snorre H. Christiansen, Jay Gopalakrishnan, Johnny Guzmán +1

We construct conforming finite element elasticity complexes on the Alfeld splits of tetrahedra. The complex consists of vector fields and symmetric tensor fields, interlinked via t…

A pressure-robust discretization of Oseen's equation using stabilization in the vorticity equation

Naveed Ahmed, Gabriel R. Barrenechea, Erik Burman +3

Discretization of Navier-Stokes' equations using pressure-robust finite element methods is considered for the high Reynolds number regime. To counter oscillations due to dominating…
