In 1D horizontal line picture V(x) values are displayed by
the red color and n(x) values are displayed by the green color.
1D pictures for different time moments are rendered in the vertical direction
to show transient processes. For dx = 0.01 you can see alternance
(inclined lines are inhomogeneous and non parallel). Full ring length is L = 1024 dx.
