Скачать или смотреть Integrating 2D Electric Field Lines from few point charges

In this tutorial I will explain how to perform calculation of electric field lines (streamlines) in 2D case with SCIPY library with Python. For this task I will calculate electric field from few point charges on the 2 dimensional grid and then will calculate and plot corresponding Electric Field lines.
This task is very similar to to the professional MHD calculations, because we do not know the value in any point of the space, but only in the mesh-grid, and I will explain how to work with this problem.
I will give short example of using different ode solvers from scipy library a finally will plot smooth electric field lines. 3D case will be considered later.
