SAGEST Center /ˈseɪdʒɪst/
(Center for Stochastic Simulations of Ablative Geometries with Error-Learning in Space and Time)
We are a center partnered under the Predictive Science Academic Alliance (PSAA) which is funded by DOE to advance science-based modeling and simulation. The Center aims to achieve trusted predictions of large-scale, complex multiscale dynamical systems at extreme conditions.
"UVA Engineering is proud to be the home of SAGEST. The groundbreaking advances in simulation and AI that SAGEST will achieve are poised to address critical national needs in hypersonics. SAGEST embodies our mission to advance engineering for the greater good." Dr. Jennifer L. West, Dean of Engineering and Applied Science, University of Virginia.
"The SAGEST Center provides a new computational modeling framework, reinforced by AI, to quantify uncertainty in predictions of complex dynamical systems under extreme environments, where physical experiments are infeasible. The research is critical for aerospace applications like hypersonic re-entry and other engineering challenges. As the SAGEST Center hub, UVA connects with partners at The Ohio State University, University of Utah, University of Minnesota, and University of Iowa, to drive collaborative innovation and amplify impact through shared expertise, joint initiatives, and dynamic engagement. I’m proud to help launch this center and look forward to all the ways the SAGEST Center will advance innovative research and education." Dr. Lori L. McMahon, Vice President for Research, University of Virginia.
We are developing a trustworthy predictive system that utilizes embedded near-ab-initio simulations to make predictions with quantified uncertainty in extreme regimes where physical experimental validation is unavailable. We will demonstrate the predictive system to a hypersonic vehicle to enhance our understanding of ablation under transient dynamics, mitigate errors using physics-based AI, and utilize data assimilation to improve computational fluid dynamics (CFD) predictions.
The SAGEST Center is one of nine centers intended to advance U.S. science-based modeling and simulation capabilities through an academic alliance (PSAAP), an initiative of the National Nuclear Security Administration/DOE.
Our home is in the University Discovery Park at North Fork of Charlottesville, a vibrant, state-of-the-art setting that inspires our researchers, students, and staff!
