smod_equil_rotating_plasma_cylinder Submodule

This submodule defines a cylindrical equilibrium, resembling a rotating plasma cylinder. The geometry can be overridden using the parfile.

This equilibrium is taken from Nijboer, R. J., Holst, B., Poedts, S., & Goedbloed, J. P. (1997). Calculating magnetohydrodynamic flow spectra. Computer physics communications, 106(1-2), 39-52.

Note

Default values are given by

  • k2 = 1
  • k3 = 0
  • cte_rho0 = 1 : used to set the density value.
  • cte_p0 = 0.1 : used to set the pressure.
  • p1 = 8 : sets the constant a21.
  • p2 = 0 : sets the constant a22.
  • p3 = 0 : sets the constant a3.
  • p4 = 1 : sets the constant b21.
  • p5 = 0 : sets the constant b22.
  • p6 = 0 : sets the constant b3.

and can all be changed in the parfile.
