Hi,
I have been running several simulations with an input density of 10^8 m^-3 and ion flow vx=8000 m/s. The electron density results show wake regions with a negative density. Do you have any ideas on how I may be able to fix this?
Moreover, the electron density wake shows a circular structure like an annulus around the spacecraft where the ion wake shows a nice V-shape wake. Do you have any ideas on how I may fix this? The ion wake shows a density enhancement in the mid wake where it should show a depletion. Any thoughts about these concerns would be greatly appreciated.
Thank you very much for your concern.
Sincerely,
Robert

In fact, my main problem is that I keep getting a negative density. Any ideas?
Thanks,

Nevermind. The negative density is for negative charges…ooops :Z
