VectorFieldAnimation

Simple class that makes it easy to simulate a Vector Field through an matplotlib animation

Requirements

This class makes use of some Python's modules Numpy and MatPlotLib.

Quick With Predefined Vector Field

This run the predefined vector field.

    import sys
    path = r"Directory/Path/Where/The/vectorfieldanimation.py/Is"
    sys.path.insert(1,path)

    # Importing the VectorFieldAnimation.py
    import vectorfieldanimation as vfa

    # Instancianting Our VectorFieldAnimation Object
    vfaObject = vfa.VectorFieldAnimation()

    # Running the simulation and animation
    vfaObject.animate()

Quick Set Up

Now let's set our Vector Field.

    import sys
    path = r"Directory/Path/Where/The/VectorFieldAnimation.py/Is"
    sys.path.insert(1,path)

    # Importing the VectorFieldAnimation.py
    import vectorfieldanimation as vfa

    # Setting Up Our Vector Field
    import numpy as np # Because we always need it

    # Sets Our 3D Space and the vectors tails
    x_axis = np.arange(-2,2,0.5)
    y_axis = np.arange(-2,2,0.5)
    z_axis = np.arange(-2,2,0.5)
    spaceMesh = [x_axis, y_axis, z_axis]

    # Setting the Vector Components Functions in terms of x,y,z and time
    # Remember, x,y and z are Numpy arrays, so use Numpy functions!!
    x_component = "4*time*x"
    y_component = "-2*(time**2)*y"
    z_component = "4*np.multiply(x,z)"
    componentsFunctions = [x_component, y_component, z_component]

    # Instancianting Our VectorFieldAnimation Object
    vfaObject = vfa.VectorFieldAnimation(space=spaceMesh, vectorComponents=componentsFunctions, length=0.3, animationDuration=2)
    # animationDuration must be in seconds and length is the vectors lengths

    # Running the simulation and animation
    vfaObject.animate()
