A Robust Multigrid Method for Isogeometric Analysis using Boundary Correction
Clemens Hofreither, Stefan Takacs, Walter Zulehner
We consider geometric multigrid methods for the solution of linear systems arising from isogeometric discretizations of elliptic partial differential equations. For classical finit…

Convection-adapted BEM-based FEM
Clemens Hofreither, Ulrich Langer, Steffen Weißer
We present a new discretization method for homogeneous convection-diffusion-reaction boundary value problems in 3D that is a non-standard finite element method with PDE-harmonic sh…
