Code in getting started guide doesn't work about pyelastica HOT 6 CLOSED

Hi @davenpi ,

Thank you for pointing out the errors. We will fix getting started guide soon. But for now here is the code you can use.

direction = np.array([0.0, 1.0, 0.0])
normal = np.array([1.0, 0.0, 0.0])
rod1 = CosseratRod.straight_rod(
    n_elements = 50,                               # number of elements
    start = np.array([0.0, 0.0, 1.0]),     # Starting position of first node in rod
    direction = direction,     # Direction the rod extends
    normal = np.cross(direction, normal),      # normal vector of rod
    base_length=0.5,                           # original length of rod (m)
    base_radius=10e-2,                         # original radius of rod (m)
    density = 1e3,                             # density of rod (kg/m^3)
    nu = 1e-3,                                 # Energy dissipation of rod
    youngs_modulus = 1e7,                                   # Elastic Modulus (Pa)
    poisson_ratio = 0.495,                     # Poisson Ratio
)

Thanks! FYI I ran into similar trouble in the post processing section of the Slithering Snake example notebook. There it seems that the results should be plotted but no plots get produced by running the code as is. From the wording it seems like there should be some visual output or am I off base?

@davenpi I run the Slithering Snake example notebook on binder and it outputs a snake velocity plot and a video showing the snake motion. Where did you run the notebook?

I'm running it in a Colab notebook. Everything before the screenshot works. The problem is the "analysis functions" import in the compute_and_plot_velocity function. My thinking was that this notebook should generate plots in a self contained manner but it seems that I need to define my own module to make this work. Is that correct?

You don't need to define your own module if you just add analysis_functions in the same directory as the notebook. Let me know if you have any other questions.
