The \Gls{fpakc} is a simulation tool that models species in plasma (ions, electrons and neutrals) following the trajectories of macro-particles as they move and interact between them and the boundaries of the domain.
|
||||
Particles properties are scattered into a finite element mesh in 1, 2 or three dimensions, with the possibility to choose different geometries.
|
||||
The official repository can be found at: \url{https://gitlab.com/JorgeGonz/fpakc.git}.
|
||||
The code is currently in very early steps of development and further improvements are expected very soon.

\section{The Particle Method}
|
||||
\Gls{fpakc} uses macro-particles to simulate the dynamics of different plasma species (mainly ions, electrons and neutrals).
|
||||
These macro-particles could represent a large amount of real particles.
|
||||
For now own, macro-particles will be referred as just particles by abusing of language.

||||
For now own, macro-particles will be referred as just particles by abuse of language.
|
||||
During the initiation phase, the input and mesh file(s) are reading.
|
||||
If an initial distribution for a species is specified in the input file, particles to match that distribution are loaded into the cells.
|
||||
|
||||
The general steps performed in each iteration are:
|
||||
\begin{enumerate}
|
||||
\item Firstly, new particles are introduced into the domain as specified in the input file.
|
||||
\item Particles are then pushed accounting for possible acceleration by external forces.
|
||||
During this process, if a particle changes cell it is found using the connectivity between elements.
|
||||
If a particle encounters a boundary instead a new cell, the interaction between the boundary and the wall is computed.

||||
During this process, if a particle changes cell, it is found using the connectivity between elements.
|
||||
If a particle encounters a boundary instead a new cell, the interaction between the boundary and the wall are computed.
|
||||
A particle may abandon the computational domain and is no longer accounted for.
|
||||
\item Next, collisions for the particles inside each cell are carried out.
|
||||
This may include different collision processes for each particle.

\section{Find new cell}
|
||||
Once the position and velocity of the particle are updated, the new cell that contains the particle is searched.
|
||||
This is done by a neighbor search, starting from the previous cell containing the particle.
|
||||
In the process of finding the new cell, it is possible that a particle encounters a boundary.

This is done by a neighbour search, starting from the previous cell containing the particle.

In the process of finding the new cell, a particle might encounter a boundary.

When the particle interacts with the boundary, the particle may continue its life in the simulation or might be eliminated from it.
|
||||
Once that the new cell is found or that the particle life has been terminated, the pushing is complete.
|
||||
If a secondary mesh is used for the Monte-Carlo Collision method, the new cell in that mesh in which the particle reside is also found by the same method, although no interaction with the boundaries is accounted for this step.

\section{Variable Weighting Scheme\label{sec:weightingScheme}}
|
||||
One of the issues in particle simulations, specially for axial-symmetrical cases, is that due to the disparate volume of cells, specially close to the axis, the statistics in some cells is usually poor.
|
||||
To try to fix that, the possibility to include a Variable Weighting Scheme in the simulations is available in \Gls{fpakc}.
|
||||
These schemes detect when a particle change cells and split it if necessary to improve statistics.
