Dynamics include damping and forcing. The scripts build upon the functionality of [`DynamicalSystems.jl`](http://github.com/JuliaDynamics/DynamicalSystems.jl) package.\n\n![logo](https://user-images.githubusercontent.com/7112768/122657073-866b8580-d1a3-11eb-88cc-27189a85d37c.gif)\n\n\n## Instructions\n\nFirst you need to [install Julia](https://julialang.org/downloads/). We suggest using Julia version 1.6 or later.\n\nThen clone the repository, e.g.,\n\n```\ngit clone https://github.com/navidcy/double_pendulum.git\n```\n\nEnter the directory you've cloned the repository in, e.g., \n\n```\ncd double_pendulum\n```\n\nand run\n\n```\njulia --project= -e 'using Pkg; Pkg.instantiate()'\n```\n\nto download all required dependencies. Afterwards, run\n\n```\njulia --project double_pendulum_logo.jl\n```\n\nto produce the logo above or \n\n```\njulia --project double_pendulum.jl\n```\n\nto 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.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnavidcy%2Fdouble_pendulum","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnavidcy%2Fdouble_pendulum","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnavidcy%2Fdouble_pendulum/lists"}
