SUMMARY:Computational Magnetohydrodynamics for Stellarators\, Prelimin
 ary Exam\, Sanket Patil\, Physics PhD Graduate Student
DESCRIPTION:Stellarators\, a type of magnetic confinement fusion devic
 e\, may be able to sustain steady-state plasmas due to their favorable
  macro-stability properties. Positive results from optimized stellarat
 or experiments and recent success in stellarator optimization have rej
 uvenated the interest in the concept. However\, the feasibility of opt
 imized plasma configurations is contingent on quiescent behavior on ma
 cro scales and may be assessed using computational nonlinear magnetohy
 drodynamics (MHD). Therefore\, the NIMSTELL code has been developed to
  address the need to model non-ideal MHD in stellarators. In this talk
 \, the progress made on the application of NIMSTELL to stellarators wi
 ll be presented\, including: (1) An interface with the DESC code to ob
 tain 3D ideal MHD equilibria as initial conditions\; (2) Preconditione
 r improvements for efficient stellarator calculations\; and (3) Result
 s from benchmarking and troubleshooting. Additionally\, future steps t
 owards completing experimentally relevant calculations and understandi
 ng the underlying physics will be discussed.
