smod_equil_resistive_homo Submodule

This submodule defines a simple, homogeneous medium in Cartesian geometry with a constant resistivity value. The geometry can be overridden using the parfile.

This equilibrium is taken from section 14.3, p. 550 in Goedbloed, H., Keppens, R., & Poedts, S. (2019). Magnetohydrodynamics of Laboratory and Astrophysical Plasmas. Cambridge University Press. DOI.

Note

Default values are given by

  • k2 = 0
  • k3 = 1
  • cte_rho0 = 1 : used to set the density value.
  • cte_B02 = 0 : used to set the By value.
  • cte_B03 = 1 : used to set the Bz value.
  • beta = 0.25 : used to constrain the temperature value.
  • fixed resistivity value of 0.001

and can all be changed in the parfile.
