Full-Orbit CUda Solver, a new iteration of the code to simulate the behavior of particles inside nuclear fusion reactors.

Hi there , I'm Michel

Todos recojan los chelines, ¡que es bajanda!

I love programming as a hobby. Most of my programming projects come from finding something that I like and I wonder if I could do it too. This is how I got involved with web development and Telegram Bots.

Some of the programming languages and technologies that I have the most experience with are

On the personal side I like singing 🎤 and playing guitar 🎸 (I'm not very good at it tho'). I also like video games 🎮, my all-time favorite is Don't Starve.

Out of boundaries and free particles

Currently, the implementation of the magnetic field returns nan if the position of interpolation is outside the area of the defined grid. If a particle leaves the area where the magnetic field is defined, then it gets a nan value that terminates the integration.

This behavior is desired in some cases, but maybe not in general. For NBI injections we want particles to come from the outside and then stop tracking them if they leave the reactor, but not at the beginning when they are outside but going in.

Also, in the case of the uncharged particles we don't even need the magnetic field in the first place, they could just move freely.

What would be the best approach to deal with these situations?

Atomic Processes Documentation

Add documentation for the atomic processes module, both regarding the physics involved and the implementation details. For the first one, the implementation is based on the work by C.F. Clauser [1].
