Exploiting repeated matrix block structures for more efficient CFD on modern supercomputers
Josep Plana-Riu, F. Xavier Trias, Ãdel Alsalti-Baldellou +3
Computational Fluid Dynamics (CFD) simulations are often constrained by the memory-bound nature of sparse matrix-vector operations, which eventually limits performance on modern hi…

Stable self-adaptive timestepping for Reduced Order Models for incompressible flows
Josep Plana-Riu, Henrik Rosenberger, Benjamin Sanderse +1
This work introduces RedEigCD, the first self-adaptive timestepping technique specifically tailored for reduced-order models (ROMs) of the incompressible Navier-Stokes equations. B…
