In this repository, I've crafted a simple molecular dynamics code in Julia that simulate a Lennard-Jones interacting atoms at room temperature. This project represented a valuable chance for me to delve deeper into this high-level but fast programming language, and by sharing I hope it proves to be beneficial for you as well.
The md.jl file within the examples directory demonstrates the simulation of 100 Helium atoms within the simulation box.
To execute this example, please utilize the following command:
$ julia md.jl
