Mean Mesh Adaptation for Efficient CFD Simulations with Operating Conditions Variability
Hugo Dornier, Olivier P Le Maître, Pietro M Congedo +3
When numerically solving partial differential equations, for a given problem and operating condition, adaptive mesh refinement (AMR) has proven its efficiency to automatically buil…
Accelerating hypersonic reentry simulations using deep learning-based hybridization (with guarantees)
Paul Novello, Gaël Poëtte, David Lugato +2
In this paper, we are interested in the acceleration of numerical simulations. We focus on a hypersonic planetary reentry problem whose simulation involves coupling fluid dynamics…
Goal-Oriented Sensitivity Analysis of Hyperparameters in Deep Learning
Paul Novello, Gaël Poëtte, David Lugato +1
Tackling new machine learning problems with neural networks always means optimizing numerous hyperparameters that define their structure and strongly impact their performances. In…
Assessment of a non-conservative four-equation multiphase system with phase transition
Paola Bacigaluppi, Julien Carlier, Marica Pelanti +2
This work focuses on the formulation of a four-equation model for simulating unsteady two-phase mixtures with phase transition and strong discontinuities. The main assumption consi…
A Taylor Based Sampling Scheme for Machine Learning in Computational Physics
Paul Novello, Gaël Poëtte, David Lugato +1
Machine Learning (ML) is increasingly used to construct surrogate models for physical simulations. We take advantage of the ability to generate data using numerical simulations pro…
Leveraging Local Variation in Data: Sampling and Weighting Schemes for Supervised Deep Learning
Paul Novello, Gaël Poëtte, David Lugato +1
In the context of supervised learning of a function by a neural network, we claim and empirically verify that the neural network yields better results when the distribution of the…
A surrogate-based optimal likelihood function for the Bayesian calibration of catalytic recombination in atmospheric entry protection materials
Anabel del Val, Olivier P. Le Maître, Olivier Chazot +2
This work deals with the inference of catalytic recombination parameters from plasma wind tunnel experiments for reusable thermal protection materials. One of the critical factors…
