Latent Space Simulation for Carbon Capture Design Optimization

1 code implementation22 Dec 2021 Brian Bartoldson, Rui Wang, Yucheng Fu, David Widemann, Sam Nguyen, Jie Bao, Zhijie Xu, Brenda Ng

This raises the possibility of a fast, accurate replacement for a CFD simulator and therefore efficient approximation of the IAs required by CCS design optimization.

Efficient nonlinear manifold reduced order model

no code implementations13 Nov 2020 Youngkyu Kim, Youngsoo Choi, David Widemann, Tarek Zohdi

Traditional linear subspace reduced order models (LS-ROMs) are able to accelerate physical simulations, in which the intrinsic solution space falls into a subspace with a small dimension, i. e., the solution space has a small Kolmogorov n-width.

A fast and accurate physics-informed neural network reduced order model with shallow masked autoencoder

no code implementations25 Sep 2020 Youngkyu Kim, Youngsoo Choi, David Widemann, Tarek Zohdi

A speedup of up to 2. 6 for 1D Burgers' and a speedup of 11. 7 for 2D Burgers' equations are achieved with an appropriate treatment of the nonlinear terms through a hyper-reduction technique.
