• -2dplot:
  Branches to the section 2dplot, where you can plot selected components of 3D-Fields over a plane as an aequivalue plot.
• -energy:
  Branches to the section -energy, where you can compute the stored energy in resonant or time dependent fields.
• -lintegral:
  Branches to the section lintegral, where you can compute line integrals of fields.
• -wlosses:
  Branches to the section -wlosses, where you can compute wall losses from magnetic fields via the perturbation formula.
