# Double Pendulum
Julia scripts to make double pendulum animations. Dynamics include damping and forcing. The scripts build upon the functionality of [`DynamicalSystems.jl`](http://github.com/JuliaDynamics/DynamicalSystems.jl) package.
## Instructions
First you need to [install Julia](https://julialang.org/downloads/). We suggest using Julia version 1.6 or later.
Then clone the repository, e.g.,
```
git clone https://github.com/navidcy/double_pendulum.git
```
Enter the directory you've cloned the repository in, e.g.,
```
cd double_pendulum
```
and run
```
julia --project= -e 'using Pkg; Pkg.instantiate()'
```
to download all required dependencies. Afterwards, run
```
julia --project double_pendulum_logo.jl
```
to produce the logo above or
```
julia --project double_pendulum.jl
```
to produce a series of animations demonstrating the normal modes of the double pendulum without forcing nor dissipation and how we can excite these normal modes in the presence of forcing and dissipation.
