xmpl3d03, 3rd 'example' data file for CPO3D
Orbit of a proton outside a charged sphere.
The proton starts with a kinetic energy of 0.25 eV, at a distance of 2 (the unit of distance is arbitrary for this simulation) from the centre of a sphere of radius 1 and at a voltage of -1. The orbits are ellipses.
(This simulation has cylindrical symmetry and so can be solved more quickly and accurately with CPO2D).
