"Challenges of Lagrangian Simulations for Gyrokinetics"

by George Wilkie

Friday, December 7, 2012 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Professor William Dorland

Gyrokinetics is a regime of plasma physics to study small-scale turbulence in some astrophysical and laboratory plasmas. The Lagrangian formalism, where the method of characteristics is utilized to solve a multidimensional PDE, is well-suited for the resulting kinetic equation. This talk makes clear the choices made to build up a particle-in-cell algorithm from this basis. This algorithm is embodied in the upgraded GSP code, from which some test cases will be presented, as well as challenges currently facing successful extension to a fully capable 3D gyrokinetic simulation tool.
