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…

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…
