Exploring Physical Latent Spaces for High-Resolution Flow Restoration

no code implementations21 Nov 2022 Chloe Paliard, Nils Thuerey, Kiwon Um

We explore training deep neural network models in conjunction with physics simulations via partial differential equations (PDEs), using the simulated degrees of freedom as latent space for a neural network.

Autonomous Shaping of Latent-Spaces from Reduced PDEs for Physical Neural Networks

no code implementations29 Sep 2021 Chloé Paliard, Nils Thuerey, Marco Cagnazzo, Kiwon Um

In contrast to previous work, we do not constrain the PDE solver but instead give the neural network complete freedom to shape the PDE solutions as degrees of freedom of a latent space.

ScalarFlow: A Large-Scale Volumetric Data Set of Real-world Scalar Transport Flows for Computer Animation and Machine Learning

no code implementations20 Nov 2020 Marie-Lena Eckert, Kiwon Um, Nils Thuerey

In this paper, we present ScalarFlow, a first large-scale data set of reconstructions of real-world smoke plumes.

Solver-in-the-Loop: Learning from Differentiable Physics to Interact with Iterative PDE-Solvers

3 code implementations NeurIPS 2020 Kiwon Um, Robert Brand, Yun, Fei, Philipp Holl, Nils Thuerey

Finding accurate solutions to partial differential equations (PDEs) is a crucial task in all scientific and engineering disciplines.

Learning Similarity Metrics for Numerical Simulations

1 code implementation ICML 2020 Georg Kohl, Kiwon Um, Nils Thuerey

We propose a neural network-based approach that computes a stable and generalizing metric (LSiM) to compare data from a variety of numerical simulation sources.

Learning Time-Aware Assistance Functions for Numerical Fluid Solvers

no code implementations ICLR 2020 Kiwon Um, Yun (Raymond) Fei, Philipp Holl, Nils Thuerey

While our approach is very general and applicable to arbitrary partial differential equation models, we specifically highlight gains in accuracy for fluid flow simulations.
