Scalable and Accurate Simulation of Magnetized Plasmas

Ilon Joseph | 20-ERD-038

Executive Summary

The goal of this project is to develop advanced finite element methods for plasma simulations at the edge of magnetically confined fusion devices. This project will not only ensure the nation's present investment in high-performance boundary plasma simulation capabilities can resolve key physical and mathematical issues and move to next-generation exascale computing platforms, but also open new possibilities for other high-energy-density science applications.
