I have just tested the thruster shell and it seems to work correctly for me with SPIS 6.1 (tested in 3 different simulations with differents thrusters and geommetry).
I can give you some comments/warning on the use of these shells. TS have been developped to monitor the angular distribution on the flux of ions on on-ground experiments thus:
- the current of electrons is not monitored (the current of droplet yes)
- in case of more than one thruster, only one thruster is monitored (the last one in the list)
- the results plot in the live monitoring are in log scale thus, if you read -5 on the y scale, it should be understood as 10^-5 A/m²
If you can give more informations on the specific issues of your simulation regarding TS use, I could be more precise in my answer.
Thaks for your feedbacks.
