SymMePlot

PyPI Tests

SymMePlot is a visualization tool designed for mechanical systems created using the mechanics module in SymPy, sympy.physics.mechanics.

The sympy.physics.mechanics module allows users to define mechanical systems symbolically to derive their analytic equations of motion. During this process, users can construct various objects such as reference frames, points, bodies, and more.

SymMePlot enhances this process by providing a way to visualize these constructed objects. It integrates with visualization backends like Matplotlib, and creates visual representations based on the parametrization of the symbols involved in the system.

SymMePlot is available on both PyPI and Conda-Forge. To install the latest release including Matplotlib from PyPI, run: :: bash pip install symmeplot matplotlib

Usage

Most of your programs are expected to follow this structure: 1. Creation of the system in sympy using the objects from sympy.physics.mechanics. 2. Initiate a Scene with the inertial frame and absolute origin. 3. Add your frames, vectors and points to the plotter instance. 4. Lambdify and evaluate the system. 5. Plot the system.

Below is a basic example of how this looks in practise: ```python import numpy as np from symmeplot.matplotlib import Scene3D from sympy.physics.mechanics import Point, ReferenceFrame, dynamicsymbols

Create the system in sympy

N = ReferenceFrame("N") A = ReferenceFrame("A") q = dynamicsymbols("q") A.orientaxis(N, N.z, q) N0 = Point("N0") v = 0.2 * N.x + 0.2 * N.y + 0.7 * N.z A0 = N0.locatenew("A_0", v)

Create the instance of the scene specifying the inertial frame and origin

scene = Scene3D(N, N0, scale=0.5)

Add the objects to the system

scene.addvector(v) scene.addframe(A, A0, ls="--") scene.add_point(A0, color="g")

Evaluate the system.

scene.lambdifysystem(q) scene.evaluatesystem(0.5)

Plot the system

scene.plot()

You can also animate this system.

ani = scene.animate(lambda q: (q,), frames=np.linspace(0, 2 * np.pi, 60)) ani.save("animation.gif", fps=30) ```
