Hi, Does anyone have any experience in using SPIS with low electron density? I am trying to model the plasma at Saturn which has a density of about 10^3 m^-3 and a temperature of about 10eV. This has a Debye length of about 230m. The potential I would expect, (in fact see in data), is about 20eV. SPIS seems to have difficulty with these sorts of numbers. Is there a limit to what plasma I can model with SPIS?
