[Archive] multi-zone modelling

Message by Enrico Sain:
I’m trying to model a spacecraft with high voltage exposed electrodes on the solar arrays. The spacecraft orbits around the Earth in a high density ionospheric environment (n=1e11 /m^3 Te=0.2 eV Ti=0.1 eV).
I was thinking about using a hybrid multi-zone volume distribution for electrons and a PIC Volume distribution for ions with a nonlinear Poisson solver.
In your opinion, what is the best way of modelling this kind of problem?
Best Regards,

I’m trying to model my problem as described in the previous post.
During the simulation I get the following exception:
Exception in thread Thread-2:

What does it mean? Please, I would really appreciate any kind of help!
