A close synergy b etween simulation\, theory\, and experiment\, (including data assimilation ) led to this advance. However\, if we were to design a new device at a ne w operating point outside parameters covered by the experiments\, we lack the ‘first principle’ predictive capabilities that enable such a desig n. This is because inertial and magnetically confined fusion systems are f ar from an equilibrium state and can span many plasma regimes Behind all o f these challenges in building ‘first principle’ models is dimensional ity.\n\nTo address this challenge\, the Center for Hierarchical and Robust Modeling of Non-Equilibrium Transport (CHaRMNET) was created. CHaRMNET\, a DoE Mathematical Multifaceted Integrated Capability Center\, will develo p mathematical tools that enable ‘first principle’ effects within the design loop of fusion energy systems. CHaRMNET will exploit structure with in models to mitigate the challenges of dimensionality and to bridge wide ranges of length and time scales in plasma science. The challenge of dimen sionality is pervasive throughout computational science and refers to the observation that the resources to solve a problem on a computer scale expo nentially with the dimensions. Fundamental plasma models are 7-dimensional and are presently computationally intractable for the engineering scale o f plasma systems. In this talk\, I will give an overview of the various th rusts in CHaRMNET to address this challenge\, with a focus on Multi-Scale Modeling.\n\nSpeaker(s): Dr. Andrew Christlieb\, \n\nAgenda: \n3:30 pm Int roduction\n\n3\;35 pm Start of talk\n\n4:30 pm event ends\n\nALL times are in EST/EDT\n\nRoom: 133\, Bldg: Chrysler Center\, 2121 Bonisteel Blvd\, U niversity of Michigan\, Ann Arbor\, Michigan\, United States\, 48109\, Vir tual: https://events.vtools.ieee.org/m/349694 LOCATION:Room: 133\, Bldg: Chrysler Center\, 2121 Bonisteel Blvd\, Universi ty of Michigan\, Ann Arbor\, Michigan\, United States\, 48109\, Virtual: h ttps://events.vtools.ieee.org/m/349694 ORGANIZER:hipple@msu.edu SEQUENCE:10 SUMMARY:Moving to Address the Curse of Dimensionality to Enable ‘First Pr inciple’ Optimal Design in Fusion Systems URL;VALUE=URI:https://events.vtools.ieee.org/m/349694 X-ALT-DESC:Description: <br /><p>The seminar will be web-simulcast via Zoom :</p>\n<p><a href="https://umich.zoom.us/j/91810335233">https://umich.zoom .us/j/91810335233</a></p>\n<p>Passcode: MIPSE</p>\n<p>Recent advances at t he National Ignition Facility (NIF) and their achievement of thermal nucle ar burn represents an exciting advancement in fusion energy systems.
