Diagram of different reconnection scenarios versus normalized reconnecting current layer thickness δ_i=L/d, and Lundquist number S_L. Other designations in the figure are the following: δ_SP – current sheet thickness predicted by Sweet-Parker model; δ_PL – resistive skin depth for plasmoid; S_C – critical value of the Lundquist number for the onset of plasmoid instability. Also shown are the parameter range for several plasmas of interest in space weather research: the Earth magnetotail, the solar chromosphere, the solar tachocline and the solar corona. The different methods and codes available in SWIFF are also set in the diagram according to their domain of applicability. All regimes of reconnection are covered by SWIFF.
