smod_equil_constant_current Submodule

This submodule defines an equilibrium in cylindrical geometry with a constant axial current. The geometry can be overridden using the parfile.

This equilibrium is taken from Kerner, W. (1989). Large-scale complex eigenvalue problems. Journal of Computational Physics, 85(1), 1-85.

Note

Default values are given by

  • k2 = -2
  • k3 = 0.2
  • j0 = 0.125 : used to set the current.
  • cte_rho0 = 1 : used to set the density.
  • cte_B03 = 1 : used to set the Bz value.

and can all be changed in the parfile.
