Functions for Maxwellian and kappa distribution functions

[namurphy]

Particle distribution functions are used pretty commonly in plasma physics, and there are analytical expressions for Maxwell-Boltzmann and kappa distributions. It would be great to create functions for these distributions in the physics subpackage.

Hi, I'd like to take care of this one.
I'll try to implement :

• functions with arg {T, V_dift, v} which return f(v) (add $\kappa$ for the Kappa function)
• A generator, creating a particle which velocity corespond to the discribution function

I'm not sure if I can do it all by myself... We'll see ! :)

Awesome! For the particles, could you also try to tie it to that PIC `species` class and try to make it return velocities for multiple particles? I'll try to help out as I can :) 12.09.2017 09:51 "antoinelpp" <notifications@github.com> napisał(a):

Anyone want to add Kappa distributions so we can close this one out? Or got any tips about Kappa distributions and what they're supposed to do? (I've never used them).

I sorted out the kappa velocity distribution functions (both 1D and 3D). This issue is nearly done.

I believe #141 and #171 close this issue. Subsequent testing and verification for the kappa distribution should fall under #186
