Linearized Aeroelastic Computations in the Frequency Domain Based on Computational Fluid Dynamics
David Amsallem, Daniel Neumann, Youngsoo Choi +1
An iterative, CFD-based approach for aeroelastic computations in the frequency domain is presented. The method relies on a linearized formulation of the aeroelastic problem and a f…
Real-time solution of computational problems using databases of parametric linear reduced-order models with arbitrary underlying meshes
David Amsallem, Radek Tezaur, Charbel Farhat
A comprehensive approach for real-time computations using a database of parameterized linear reduced-order models (ROMs) is proposed. The method proceeds by sampling offline ROMs f…
Robust Model Reduction by -norm Minimization and Approximation via Dictionaries: Application to Linear and Nonlinear Hyperbolic Problems
Remi Abgrall, David Amsallem
We propose a novel model reduction approach for the approximation of non linear hyperbolic equations in the scalar and the system cases. The approach relies on an offline computati…
Gradient-based Constrained Optimization Using a Database of Linear Reduced-Order Models
Youngsoo Choi, Gabriele Boncoraglio, Spenser Anderson +2
A methodology grounded in model reduction is presented for accelerating the gradient-based solution of a family of linear or nonlinear constrained optimization problems where the c…
Projection-based model reduction for contact problems
Maciej Balajewicz, David Amsallem, Charbel Farhat
To be feasible for computationally intensive applications such as parametric studies, optimization and control design, large-scale finite element analysis requires model order redu…
