## Multibody modeling in ModelingToolkit using **Multibody.jl**

I’m happy to announce that the repository of [Multibody.jl has just been made public](https://github.com/JuliaComputing/Multibody.jl). _Multibody.jl_ is a component library for ModelingToolkit that allows you to model and simulate multibody-systems (3D mechanics).

The package is registered in the JuliaHub registry and can be installed using the [installation instructions](https://help.juliahub.com/multibody/dev/#Installation).

Check out the [example overview in the documentation](https://help.juliahub.com/multibody/dev/#Example-overview) for some cool animations, and check out the rest of the examples for even more cool stuff.

_Multibody.jl_ is a part of _JuliaSim_, which means that it is free to use for academics and personal use, but requires a license for professional use ([license info](https://github.com/JuliaComputing/Multibody.jl/blob/main/LICENSE)).

Here are some cool animations made by the package (using [Makie](https://github.com/MakieOrg/Makie.jl) under the hood)
