On the transmission of floating-point perturbations in flow-dependent filter-width formulations in Large-Eddy Simulation
Valerio D'Alessandro, Alessio Piccolo, Matteo Falone +1
Heterogeneous high--performance computing architectures expose numerical algorithms to perturbations arising from the non--associativity of floating--point arithmetic. In Large--Ed…

A monolithic ALE Newton-Krylov solver with Multigrid-Richardson-Schwarz preconditioning for incompressible Fluid Structure Interaction
Eugenio Aulisa, Simone Bna, Giorgio Bornia
In this paper we study a monolithic Newton-Krylov solver with exact Jacobian for the solution of incompressible FSI problems. A main focus of this work is on the use of geometric m…
