A performance comparison of continuous and discontinuous Galerkin methods with fast multigrid solvers
Martin Kronbichler, Wolfgang A. Wall
This study presents a fair performance comparison of the continuous finite element method, the symmetric interior penalty discontinuous Galerkin method, and the hybridized disconti…
Geometrically exact beam elements and smooth contact schemes for the modeling of fiber-based materials and structures
Christoph Meier, Maximilian J. Grill, Wolfgang A. Wall +1
Recently, the authors have proposed a novel all-angle beam contact (ABC) formulation that combines the advantages of existing point and line contact models in a variationally consi…
A stabilized Nitsche cut finite element method for the Oseen problem
Andre Massing, Benedikt Schott, Wolfgang A. Wall
We propose a stabilized Nitsche-based cut finite element formulation for the Oseen problem in which the boundary of the domain is allowed to cut through the elements of an easy-to-…
Geometrically Exact Finite Element Formulations for Curved Slender Beams: Kirchhoff-Love Theory vs. Simo-Reissner Theory
Christoph Meier, Wolfgang A. Wall, Alexander Popp
The present work focuses on geometrically exact finite elements for highly slender beams. It aims at the proposal of novel formulations of Kirchhoff-Love type, a detailed review of…
A Temporal Consistent Monolithic Approach to Fluid-Structure Interaction Enabling Single Field Predictors
Matthias Mayr, Thomas Klöppel, Wolfgang A. Wall +1
We present a monolithic approach to large-deformation fluid-structure interaction (FSI) problems that allows for choosing fully implicit, single-step and single-stage time integrat…
A Unified Approach for Beam-to-Beam Contact
Christoph Meier, Wolfgang A. Wall, Alexander Popp
Existing beam contact formulations can be categorized in point contact models that consider a discrete contact force at the closest point of the beams, and line contact models that…
