Phase-field modeling of brittle fracture with multi-level hp-FEM and the finite cell method [PDF]
Computational Mechanics, 2018 The difficulties in dealing with discontinuities related to a sharp crack are overcome in the phase-field approach for fracture by modeling the crack as a diffusive object being described by a continuous field having high gradients.

The hp-adaptive FEM based on continuous Sobolev embeddings: isotropic refinements [PDF]
, 2014 The aim of this paper is to present a new class of smoothness testing strategies in the context of hp-adaptive refinements based on continuous Sobolev embeddings. In addition to deriving a modified form of the 1d smoothness indicators introduced in [26]

hp-FEM for the fractional heat equation [PDF]
IMA Journal of Numerical Analysis, 2019 We consider a time-dependent problem generated by a nonlocal operator in space. Applying for the spatial discretization a scheme based on $hp$-finite elements and a Caffarelli–Silvestre extension we obtain a semidiscrete semigroup.

Wavenumber-Explicit hp-FEM Analysis for Maxwell’s Equations with Transparent Boundary Conditions [PDF]
Foundations of Computational Mathematics, 2018 The time-harmonic Maxwell equations at high wavenumber k are discretized by edge elements of degree p on a mesh of width h . For the case of a ball as the computational domain and exact, transparent boundary conditions, we show quasi-optimality of the ...

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]
, 2011 We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.
