Output for the example ALPHIE_Grid.
Found an issue when multiple injections were used with species with
different time steps.
Modification to the way to compute the ionization boundary:
The maximum number of ionizations is computed by eRel/eThreshold
(relative energy / threshold of ionization)
For each possible ionization, the probability of ionization is
computed based on the density of neutrals, cross section and effective
time divided by the number of maximum ionizations.
If an ionization takes place, the ionization energy is substracted
from the relative energy.
Documentation adapted to the new way to define geometry and pushers.
Examples are currently being tested and small modifications are being
done to include a reference output.
Merging branches and fixing a number of important issues:
- Initial particles were not being assigned to the list of particles.
- List of particles was being erased every iteration, even if species
was not pushed.
These caused issues with the calculation of collisions when a species
was frozen.
Now, things should work properly. All particles are properly added to
the volume list and the list is erased ONLY if the species has been
updated.
I hope that collisions are now properly accounted for per species 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.
First implementation of Electromagnetic pusher.
Some testing is still required.
Documentation needs to be upgraded to match the changes in this branch.
The geometry and push structure has been reworked to allow eassy adding
new pushers.
Documentation not updated yet.
Baseline for merging Cartesian pushers into one.
Now, probes check all particles in the domain.
This is done only when probes are outputed to save CPU time.
However, still some issues and distribution functions are not properly
being calculated.
The code nows offer the possibility to obtain the distribution function
for a specific species in a 3D velocity grid at a determined position.
This is a simple method that just scatter the particles in one cell into
the velocity grid.
A new option has been added in which MCC are computed with its own time
step.
If no time is provided, then the minimum time step of the simulation is
employed.
Fixed an issue in which the position in triangular an thetrahedron
elements were not correctly being computed.
Other minor issues fixed:
- Units in input file now do not use '/'.
- Collisions accuratly conserve momentum.
- Minor improvements in mass calculation in collisions.
An initial simulation time can be provided in the input file. This is
useful when restarting a simulation from a previous file. If no
initial time is provided, the value 0 is used.
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.
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.
Documentation updated properly.
3D Cartesian geometry also tested.
Documentation updated properly.
Added weighting probability in the injection of particles.
Fixed an issue in which some particles in the corner were interacting
with the axis boundary. Now the axis acts as a reflective boundary in
case a particle is wrongly assigned to it.
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.
x/r position to avoid huge fields in Radial case when r -> 0 due to
charge accumulation.
Added a Gnuplot script to plot both potential profiles extracted from
Gmsh.
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.
