Towards Data-Driven Dynamic Surrogate Models for Ocean Flow [PDF]

open access: yesProceedings of the Platform for Advanced Scientific Computing Conference, 2019
Coarse graining of (geophysical) flow problems is a necessity brought upon us by the wide range of spatial and temporal scales present in these problems, which cannot be all represented on a numerical grid without an inordinate amount of computational resources. Traditionally, the effect of the unresolved eddies is approximated by deterministic closure

Noise shielding surrogate models using dynamic artificial neural networks [PDF]

open access: yesINTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021
The optimal design methodologies in aeronautics are known to be constrained by the computational burden required by direct simulations. Due to this reason, the development of efficient metamodelling techniques represents nowadays an imperative need for the designers. In fact, surrogate models has been demonstrated to significantly reduce the number of
