Vector-Field-matplotlib

Vector fields associate a 2D vector to each point of the 2D plane. Vector fields are common in Physics as they provide solutions to differential equations. Matplotlib provides functions to visualize vector fields. To illustrate the visualization of vector fields, let's visualize the velocity flow of an incompressible fluid around a cylinder. We do not need to bother about how to compute such a vector field but only about how to show it. The pyplot.quiver() function is what we need. How the project work: Although the script is a bit long, the purely graphical part is simple. The vector field is stored in the matrices U and V: the coordinates of each vector we sampled from the vector field. The matrices X and Y contain the sample positions. The matrices X, Y, U, and V are passed to pyplot.quiver(), which renders the vector field. Note that pyplot.quiver() can take just U and V as parameters, but then the legend will show the indexes of the samples rather than their coordinates. As the vector field that we used as an illustration here the fluid flow around a shape, the shape itself is shown as follows: shape = patches.Circle((0, 0), radius = 1., lw = 2., fc = 'w', ec = 'k', zorder = 0) plt.gca().add_patch(shape) The vector field inside the cylinder does not appear; we use a masked array. We first create a mask that defines which samples should be shown. Then, we apply this mask on U and V, as shown in the script.

DISCLAIMER:The code is for educational purposes only. You can use it for educational purposes only not for commercial uses. In vector calculus and physics, a vector field is an assignment of a vector to each point in a subset of space. For instance, a vector field in the plane can be visualised as a collection of arrows with a given magnitude and direction, each attached to a point in the plane. Vector fields are often used to model, for example, the speed and direction of a moving fluid throughout space, or the strength and direction of some force, such as the magnetic or gravitational force, as it changes from one point to another point. The elements of differential and integral calculus extend naturally to vector fields. When a vector field represents force, the line integral of a vector field represents the work done by a force moving along a path, and under this interpretation conservation of energy is exhibited as a special case of the fundamental theorem of calculus. Vector fields can usefully be thought of as representing the velocity of a moving flow in space, and this physical intuition leads to notions such as the divergence (which represents the rate of change of volume of a flow) and curl (which represents the rotation of a flow).

Vect-Field-Remastered.py

From the previous code of Vector Field 2D, using arrows to represent a vector field works fairly well. But matplotlib can do better than this—it can show the streamlines of a vector field. A streamline shows how the vector field flows. In this recipe, we will show you how to create streamlines. Let's use the fluid flow example of the previous recipe. You will simply replace the arrows ( the first code of vector field ) with streamlines, as shown in the following code.
