Enhancing quasi-newton acceleration for fluid-structure interaction

HIGHLIGHTS

• who: Kyle Davis et al. from the Simulation of Large Systems, Institute for Parallel and Distributed Systems (IPVS), University of Stuttgart have published the paper: Enhancing Quasi-Newton Acceleration for Fluid-Structure Interaction, in the Journal: (JOURNAL)
• what: The authors propose two enhancements of quasi-Newton methods used to accelerate coupling iterations for partitioned fluid-structure interaction. The authors propose two new approaches-pre-scaling weight monitoring and a new so-called QR3 filter to substantially improve runtime while not affecting convergence quality. The authors evaluate these for a variety of fluid-structure interaction examples . . .
