Hi!

I would like to announce the first version of [NeutronTransport.jl](https://github.com/rvignolo/NeutronTransport.jl), a package that solves the neutron transport equation using the Method of Characteristics approximation.

It is inspired in [OpenMOC](https://github.com/mit-crpg/OpenMOC), a program developed by members of the [Computational Reactor Physics Group](http://crpg.mit.edu/) at the [Massachusetts Institute of Technology](http://web.mit.edu/). OpenMOC is in C++/Python. I have managed to code many of OpenMOC’s functionalities in NeutronTransport.jl in a very short period of time, which shows me (once again) the potential of Julia and its package ecosystem.

Regarding NeutronTransport.jl, short term goals are:

- add CSG (Constructive Solid Geometry) support.
- parallelization and many other performance enhancement techniques.

The long term goal is to add more approximations, such as Collision Probability, Discrete Ordinates and Diffusion.

I hope people can make use of this package and contribute!

Thank you!

Even though [NeutronTransport](https://github.com/rvignolo/NeutronTransport.jl) is in an early stage of development, it can already solve the [c5g7](https://www.oecd-nea.org/science/wprs/eg3drtb/NEA-C5G7MOX.PDF) benchmark!
