Relaxation of point vortex model to singly-peaked state.

Again, I made a mistake, the aspect ratio is wrong.

Relaxation of point vortex model to singly-peaked state.
Simulation of the 2-d point vortex model
as a model of the 2-d pure electron plasma under the strong magnetic field (Malmberg trap).
The dynamics is well approximated by the 2-d Euler equation.
Vortex in cell (VIC) method is used with 513x513 mesh.
N = 160,000.
The initial configuration is a single ring state with randomly located particles.

Detail of the study will be available on http://www.stat.phys.kyushu-u.ac.jp/~ryokawa/study/twodpep_intro/
