Deflation-based preconditioning for immersed finite element methods and immersogeometric analysis
Yannis Voet, Matthias Möller, Pablo Antolin +1
Trimming is a ubiquitous operation in computer-aided-design whereby parts of a geometry are merged, intersected, or simply discarded. While it grants virtually unlimited flexibilit…
A ROM-based BDDC solver for unfitted p-FEM level-set-based two-dimensional lattice structures
Gonzalo Bonilla Moreno, Giuliano Guarino, Pablo Antolin
We present a domain decomposition method for the fast simulation of large two-dimensional lattice structures described by level set functions. The method does not rely on homogeniz…
Efficient Fine-Scale Simulation of Nonlinear Hyperelastic Lattice Structures
Clément Guillet, Thibaut Hirschler, Pierre Jolivet +2
With the growing maturity of additive manufacturing, the fabrication of architected or lattice-based metamaterials has become a reality for industrial applications. These materials…
A General and Robust 3D Finite Element Dynamics Framework for Railway Vehicle-Bridge Interaction with Nonlinear Wheel-Rail Contact Modeling
Pablo Antolin, Khanh Nguyen, José M. Goicolea
A key challenge in 3D finite element models of coupled railway vehicle-bridge dynamics is the rigorous definition of kinematic constraints and the development of an efficient, robu…
