The Influence of Nitsche Stabilization on Geometric Multigrid for the Finite Cell Method
S. Saberi, G. Meschke, A. Vogel
Immersed finite element methods have been developed as a means to circumvent the costly mesh generation required in conventional finite element analysis. However, the numerical ill…
Adaptive geometric multigrid for the mixed finite cell formulation of Stokes and Navier-Stokes equations
S. Saberi, G. Meschke, A. Vogel
Unfitted finite element methods have emerged as a popular alternative to classical finite element methods for the solution of partial differential equations and allow modeling arbi…
A restricted additive Vanka smoother for geometric multigrid
S. Saberi, G. Meschke, A. Vogel
The solution of saddle-point problems, such as the Stokes equations, is a challenging task, especially in large-scale problems. Multigrid methods are one of the most efficient solv…
Accelerating Geometric Multigrid Preconditioning with Half-Precision Arithmetic on GPUs
Kyaw L. Oo, Andreas Vogel
With the hardware support for half-precision arithmetic on NVIDIA V100 GPUs, high-performance computing applications can benefit from lower precision at appropriate spots to speed…
Parallel 3d shape optimization for cellular composites on large distributed-memory clusters
Jose Pinzon, Martin Siebenborn, Andreas Vogel
Skin modeling is an ongoing research area that highly benefits from modern parallel algorithms. This article aims at applying shape optimization to compute cell size and arrangemen…
A shape optimization algorithm for cellular composites
Martin Siebenborn, Andreas Vogel
We propose and investigate a mesh deformation technique for PDE constrained shape optimization. Introducing a gradient penalization to the inner product for linearized shape spaces…
Parareal convergence for 2D unsteady flow around a cylinder
Andreas Kreienbuehl, Arne Naegel, Daniel Ruprecht +3
In this technical report we study the convergence of Parareal for 2D incompressible flow around a cylinder for different viscosities. Two methods are used as fine integrator: backw…
