Dear Shaun,

Coupling the thruster plasma with the environment is not possible with current versions of SPIS. A new version dedicated to this task is scheduled to be released before summer.

Best Regards,

I am an undergraduate conducting a project into the interaction of ion engine plumes with rarefied atmosphere and ionosphere in very low earth orbit, for example the ESA GOCE mission.

I am new to the SPIS software, and would appreciate any advice upon how to model the thruster within the non-vacuum conditions. i.e model the thruster as an emitting surface within a hypersonic low density flow of both neutral atmosphere and charged ionosphere
