\subsection{Elastic collision}
In this type of collision, particles exchange energy due to hard-sphere model.
Total energy is conserved.
Resulting velocity directions are chosen from Maxwellian distribution functions.
This interaction is useful for short-range collisions as neutral-neutral and charged-neutral elastic collisions.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Charge Exchange}
When an ion interacts with a neutral particle, an electron is exchanged between the two particles with no exchange of energy.
This is called a resonant charge-exchange.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Ionization}
\subsection{Electron Impact Ionization}
When the relative energy between a neutral and an electron is above the ionization threshold, there is a probability that the neutral particle will become ionized.
This ionization emits and additional electron
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\subsection{Recombination}
When an electron and an ion interact, there is a possibility for them to be recombined into a neutral particle.
The photon emitted by this process is not modeled yet.

To run a case, simply execute:
\begin{lstlisting}
./fpakc path-to-input-file.json
./fpakc path/to/input-file.json
\end{lstlisting}
in a command line.
in a command line from the root \acrshort{fpakc} folder.
Substitute \lstinline|path/to/input-file.json| with the path to the input file of the case you want to run.
The examples in the run directory are presented in Chapter \ref{ch:exampleRuns}.

\section{1D Cathode}
Emission from a 1D cathond in both, cartesian and radial coordinates.
Both cases insert the same amount of electrons from the minimum coordinate and have the same boundary conditions for particles and the electrostatic field.
This case is useful to ilustrate hoy \acrshort{fpakc} can deal with different geometries by just modifiying some parameters in the input file.
The same mesh file (\lstinline|mesh.msh|) is used for both cases.

\section{ALPHIE Grid system}
Two-dimensional axialsymmetry case to study the counterflow of electrons and Argon ions going trhough the ALPHIE grid system.
A \lstinline|mesh.geo| file is provided to easily modify the parameters of the grid system and generate a new mesh with \Gls{gmsh}.

\section{Flow around cylinder}
Simple case of neutral Argon flow around a cylinder in a 2D axialsymmetry geometry.
Elastic collisions between argon particles are included as default.
