Mesh sampling and weighting for the hyperreduction of nonlinear Petrov-Galerkin reduced-order models with local reduced-order bases
Sebastian Grimberg, Charbel Farhat, Radek Tezaur +1
The energy-conserving sampling and weighting (ECSW) method is a hyperreduction method originally developed for accelerating the performance of Galerkin projection-based reduced-ord…
In-situ adaptive reduction of nonlinear multiscale structural dynamics models
Wanli He, Philip Avery, Charbel Farhat
Conventional offline training of reduced-order bases in a predetermined region of a parameter space leads to parametric reduced-order models that are vulnerable to extrapolation. T…
Model Reduction Framework with a New Take on Active Subspaces for Optimization Problems with Linearized Fluid-Structure Interaction Constraints
Gabriele Boncoraglio, Charbel Farhat, Charbel Bou-Mosleh
In this paper, a new take on the concept of an active subspace for reducing the dimension of the design parameter space in a multidisciplinary analysis and optimization (MDAO) prob…
On the stability of projection-based model order reduction for convection-dominated laminar and turbulent flows
Sebastian Grimberg, Charbel Farhat, Noah Youkilis
In the literature on projection-based nonlinear model order reduction for fluid dynamics problems, it is often claimed that due to modal truncation, a projection-based reduced-orde…
Modeling, simulation and validation of supersonic parachute inflation dynamics during Mars landing
Daniel Z. Huang, Philip Avery, Charbel Farhat +3
A high fidelity multi-physics Eulerian computational framework is presented for the simulation of supersonic parachute inflation during Mars landing. Unlike previous investigations…
An Embedded Boundary Approach for Resolving the Contribution of Cable Subsystems to Fully Coupled Fluid-Structure Interaction
Daniel Z. Huang, Philip Avery, Charbel Farhat
Cable subsystems characterized by long, slender, and flexible structural elements are featured in numerous engineering systems. In each of them, interaction between an individual c…
