2D Fourier finite element formulation for magnetostatics in curvilinear coordinates with a symmetry direction
Christopher G. Albert, Oszkár Bíró, Patrick Lainer
We present a numerical method for the solution of linear magnetostatic problems in domains with a symmetry direction, including axial and translational symmetry. The approach uses…

Symplectic integration with non-canonical quadrature for guiding-center orbits in magnetic confinement devices
Christopher G. Albert, Sergei V. Kasilov, Winfried Kernbichler
We study symplectic numerical integration of mechanical systems with a Hamiltonian specified in non-canonical coordinates and its application to guiding-center motion of charged pl…
