A conforming representation composed of two-dimensional finite elements and finite Fourier series is applied to three-dimensional nonlinear non-ideal magnetohydrodynamics using a semi-implicit time-advance. The self-adjoint semi-implicit operator and variational approach to spatial discretization are synergistic and enable simulation in the extremely stiff(More)
The fully self-consistent simulation of energetic particle turbulence and transport in burning plasmas such as ITER must incorporate three new physics elements: (i) kinetic effects of thermal particles at the thermal ion gyroradius (micro scale), (ii) nonlinear interactions of many meso scale (energetic particle gyroradius) shear Alfvén waves induced by the(More)
