4e9514876e Number of collisions per collision pair
Now the number of collisions is calculated per species pair. This allows
that the randomly particles selected for collisions do not have
collisions assigned.

8006f9d768 First EM pusher
First implementation of Electromagnetic pusher.

Some testing is still required.

Documentation needs to be upgraded to match the changes in this branch.

35bd61fda9 Common scatter subroutine
All subroutines of scattering particle properties to the nodes of a
volume have been converged into one in moduleMesh.

a681b9f533 0D Grid geometry
Implementation of the 0D grid to test collisional processes.

An OMP_LOCK was added to the nodes to properly write perform the
scattering (it is weird that multiple threads work in the same node at
the same time, but in 0D happens everytime).

Added a new case to test the 0D geometry.

User Manual updated with the new options.

e25b567d36 Now the initial state has the same format as the mesh file, i.e., is
easy to use a file from a previous run without processing it into a
plain text file.

Although the previous method presented some updates for 1D small cases,
this is quite easy to do with any type of simulations and, in the
future, with different mesh formats.

a2631f6b78 Impliementation of a collision mesh which is independent for the mesh
used to scatter particles and compute the EM field.

3f91d9e1ed Reading of mesh files has been made independent from geometry and
prepared to accept different formats.

46348c86ee Improved some general things using pointers. 2021-03-28 16:52:01 +02:00
ec128902ad The integer part%sp that referenced the species index has been
substituted for a pointer to the species.

db6b0a2c03 Fixed an issue with reflection of particles in all geometries and also
assigning the normal vector in 2D and 3D.

3D Cartesian geometry is working properly, although it needs testing.

Still issue with ionization boundary.

8cf50cda68 First implementation of ionization boundary. Still some work to do. 2021-03-20 13:08:01 +01:00
ff0c09242d Fixed an issue with normal vector not being norm unit, which was causing
reflected particle velocities to increase.

ac2965621a Structure for 3D Cartesian Grid created.
Unification of boundary conditions into one file.

Some changes to input file for reference cases. This should have been
done in another branch but I wanto to commit to save progress and I
don't want to deal with tswitching branches right now, I'm very busy
watching Futurama.

4ba08e74af Method to divide collisions from a collisional iteration into multiple
pushing iterations.

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().

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.
