[Archive] asymmetry structure in final potential

SPIS
#1

Message by Fang Yang:
I have tried serveral tens of tests on SPIS RC09.

I always use a cube as a computation volume with satellite in it.
In the simluations, the final potential diagram often show an asymmetry
structure in the entire computation volume, and specially on the -z axis boundary.

I figure out some reasons:

  1. computation space not big enough
2. wrong boundary conditions
3. duration time not long enough to get equilibrium
or something else?
For example: a LEO charging problem
surfacematerial:all ITO
