Message by Martin Ding:
I am confused why we need 2 Electron populations and 2 Ion populations? I searched on the net but not found explanation. Can some one help to explain it? Thank you.

Hi,
You don’t have to use both populations. But if you want to model a double Maxwellian environment, using two populations is the way of doing it (TBC by ONERA?).
See SPIS-NUM user manual for further information.
