That's why you shouldn't use discretised simulations of smoothly analytic equations.

Why would you have dipole gravity? There isn't a charge associated with gravity. You have neutral particles that are equally affected by gravity as the charged ones. You are more likely to make progress in relating kinetic energy to gravitation than you are with charge. At least kinetic energy has a relationship to the wave nature of mass. Charge would in no way explain time dilation as it is invariant in all inertial frames. If you look at your diagrams with respect to angular momentum that is something entirely different and much more valid.

Here is something simple to start you off.
