When I change the density of plasma in “test1_Cube” from 1e6/m3 to 1e12/m3, the potential of s/c is also charged from several volts to several hundreds volts. But in my mind, the balance potential should be around 0V, that is, always keep several or low than 50V.

I got the capacity by fastcap. The msh file is transfered to qui file with my c++ program. It seems 0.1-1nF is ok. So what is the reason?
Message by Jean-Francois Roussel:
probably instabilities issues, which or more important at higher densities

would you give more documents relative or suggestion about understanding circuit model of spacecraft?maybe I can make some improvements.
