2ae4a6c785 First implementation of 2D Cartesian space.
Files and types with 'Cyl' have been changed to '2DCyl' to better
differentiate between the two types of 2D geometry.

Solvers for charged and neutral particles in 2D Cartesian space.

Added solveds for 1D neutral particles (this branch is not the place to
    do it, but it was a minor change).

User Manual updated with the new accepted options.

2a6628d529 Added and option to include an output folder name. The date and time of
creation is still appended to the folder name provided.

874d573e89 New and improved method to calculate collisions per iteration:
In each iteration, number of collisions are calculate as a REAL variable
(collFrac) and stored in each cell. The number of collisions is
calculated as FLOOR(collFrac) and, if it is >1 collisions are computed
as usual. Per each collision calculated, 1.0 is removed from collFrac

a45df9de22 Recombination process introduced. No photon creation yet. 2020-12-27 13:15:36 +01:00
9e0d1a7cc7 Final implementation of ionization process by electron impact.
Possibility to input initial species distributions (density, velocity
    and temperature) via an input file for each species.

New moduleRandom includes function to generate random numbers in
different ways (still uses) the implicit RANDOM_NUMBER().

e50cc3325b Implementation of ionization process.
Now collisions can have a different time step.

Added species name to output names as it was starting to get confusing
in Gmsh for multiple species.

Output filenames adapted to match any number of iterations.

159d1527e6 Fixed a bug related with reading information on linking species. 2020-12-22 16:52:05 +01:00
35936ea918 Implementation of charge exchange and structure for ionization
processes.

baf25c1157 New boundary condition 'wallTemperature' that simulates a reflecting
wall with constant temperature and specific heat.
2020-12-19 16:20:28 +01:00
9e3a1a771b Modification in boundary conditions:
- Now absorption scatte the particle  properties into the edge nodes.
  - New boundary condition 'transparent' subsitute old absorption.
2020-12-17 21:16:35 +01:00
2c3e25b40e Added the possibility to have different boundary conditions per species.
A boundary condition for each species must be indicated in the case
file.
This opens the door to use boundary conditions with different parameters
(for example, a wall temperature, coefficients for reflection or
 absorption...)

The examples included with the code have been updated accordently.

d3d070a367 First implementation of 1D radial case. Only charged particles taked
into account (as in 1D Cartesian case).

The 1D Cathode example case has been modified, having now 2 input files:
  - inputCart.json: Used for Cartesian coordinates
  - inputRad.json:  Used for Radial coordinates

Pusher is a Boris pusher but without z direction.

f151f3cd0e Renaming the generic 'non-analogue' scheme for 'weighting' scheme. 2020-12-13 17:04:52 +01:00
37b0139b1f Implementation of different distribution functions for velocities.
Maxwellian and Diract Delta distributions have been implemented.

The input for injection of particles should be rewritten to allow more
clear input file.
