A Non-intrusive Approach for the Imposition of Strong Dirichlet Boundary Conditions in Unfitted Boundary Meshes
J. I. Camarotti, R. Aristio, R. Rossi +2
The enforcement of essential boundary conditions is a fundamental challenge in unfitted boundary methods. This paper presents a non-intrusive, black-box strategy for imposing such…
Partitioned Co-Simulation for CAD-integrated Vibroacoustic Problems in Unbounded Domains
J. I. Camarotti, P. Le, Y. Cai +4
Vibroacoustic analysis often requires coupling structural and acoustic solvers based on different numerical formulations and discretizations, making monolithic implementations intr…
Boundary-Level-Constrained Refinement for Suppressing Trimming-Induced High-Frequency Outliers in Explicit Isogeometric Analysis
Christoph Hollweck, Lukas Leidinger, Stefan Hartmann +2
In explicit dynamics, the critical time step is governed by the maximum eigenfrequency of the semi-discrete system. In Isogeometric Analysis (IGA), open knot vectors introduce a ch…
High-Fidelity Digital Twins: Detecting and Localizing Weaknesses in Structures
Rainald Löhner, Facundo N. Airaudo, Harbir Antil +3
An adjoint-based procedure to determine weaknesses, or, more generally, the material properties of structures is developed and tested. Given a series of load cases and correspondin…
Adjoint-based Determination of Weaknesses in Structures
Facundo N. Airaudo, Rainald Löhner, Roland Wüchner +1
An adjoint-based procedure to determine weaknesses, or, more generally the material properties of structures is developed and tested. Given a series of force and deformation/strain…
Finite Element Method-enhanced Neural Network for Forward and Inverse Problems
Rishith Ellath Meethal, Birgit Obst, Mohamed Khalil +4
We introduce a novel hybrid methodology combining classical finite element methods (FEM) with neural networks to create a well-performing and generalizable surrogate model for forw…
Risk-averse design of tall buildings for uncertain wind conditions
Anoop Kodakkal, Brendan Keith, Ustim Khristenko +4
Reducing the intensity of wind excitation via aerodynamic shape modification is a major strategy to mitigate the reaction forces on supertall buildings, reduce construction and mai…
A partitioned scheme for adjoint shape sensitivity analysis of fluid-structure interactions involving non-matching meshes
Reza Najian Asl, Ihar Antonau, Aditya Ghantasala +3
This work presents a partitioned solution procedure to compute shape gradients in fluid-structure interaction (FSI) using black-box adjoint solvers. Special attention is paid to pr…
