Abstract

Jacobi, capacitor, potential field

Background discription

Just like in the differential equation of the time gap, we do finite difference time and space position. In fact, the particle equation by the finite difference method is derived. Here, we use two-dimensional finite difference form as follows:

Analysis and procedure

The subject requirements for:

The following code: Link code
design sketch：

Conclusion:

The potential field can be obtained by only calculating X-Y plane of the first quadrant: at each step to update the V operation, the second quadrant of the mirror symmetry value, and then use the three or four quadrant value of rotational symmetry.
