Graph Neural Network Based Surrogate Model of Physics Simulations for Geometry Design

no code implementations1 Feb 2023 Jian Cheng Wong, Chin Chun Ooi, Joyjit Chattoraj, Lucas Lestandi, Guoying Dong, Umesh Kizhakkinan, David William Rosen, Mark Hyunpong Jhon, My Ha Dao

Computational Intelligence (CI) techniques have shown great potential as a surrogate model of expensive physics simulation, with demonstrated ability to make fast predictions, albeit at the expense of accuracy in some cases.

An iterative multi-fidelity approach for model order reduction of multi-dimensional input parametric PDE systems

no code implementations23 Jan 2023 Manisha Chetry, Domenico Borzacchiello, Lucas Lestandi, Luisa Rocha Da Silva

It is achieved by exploiting low-fidelity models throughout the parametric space to sample points using an efficient sampling strategy, and at the sampled parametric points, high-fidelity models are evaluated to recover the reduced basis functions.
