Numerical simulati ons require fine spatial and temporal discretizations that can be computat ionally expensive.  In this talk\, I will discuss GrainNN\, an efficient and accurate reduced-order model for epitaxial grain growth in additive ma nufacturing conditions. GrainNN  is a sequence-to-sequence long-short-ter m-memory (LSTM) deep neural network that evolves the dynamics of manually crafted features. We present results in which GrainGNN can be orders of ma gnitude faster than phase field simulations\, while delivering 5%–15% po intwise error. This speedup includes the cost of the phase field simulatio ns for generating training data. GrainGNN enables predictive simulations a nd uncertainty quantification of grain microstructure for situations not p reviously possible.\nAbout the Speaker\nGeorge Biros\, Ph.D. - Professor and W. A. "Tex"' Moncrief Chair in Simulation-Based Engineering Sciences\n George Biros is the W. A. "Tex"' Moncrief Chair in Simulation-Based Engine ering Sciences in the Oden Institute for Computational Engineering and Sci ences and has Full Professor appointments with the departments of Mechanic al Engineering and Computer Science (by courtesy) at The University of Tex as at Austin.\n\nFrom 2008 to 2011\, he was an Associate Professor in the School of Computational Science and Engineering at Georgia Tech and The Wa llace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. From 2003 to 2008\, he was an Assistant professor in Mec hanical Engineering and Applied Mechanics at the University of Pennsylvani a.\n\nHe received his BS in Mechanical Engineering from Aristotle Universi ty in Greece (1995)\, his MS in Biomedical Engineering from Carnegie Mello n (1996)\, and his PhD in Computational Science and Engineering also from Carnegie Mellon (2000).  He was a postdoctoral associate at the Courant I nstitute of Mathematical Sciences from 2000 to 2003. With collaborators\, he received the ACM Gordon Bell Prize in 2003 and in 2010.\n\n \;\n\n\ n\nDr. George Biros\nMembers: remember to login to see your free ticket op tion.
