7b7a5c45ca Small improvement
Very small improvement in performance.

Still, partialDer takes too long to compute.
Trying to find ways to improve it.

ba272de4e3 DOES NOT COMPILE: Break
Small break of changing functions.
Still some geometries to change.

7f6afd6a87 Mark_1
First thing that I am kinda happy with.

Still some things to improve but at least push is good.

15d64f3e68 Passing nNodes as argument
It seems that this improves results as passing the size of the arrays as
an argument is better than getting it from self.

2486ef6316 Reduction in pushing
Reduction in 10-20% of time spend in pushing in 2DCyl thanks to
rewriting fPsi and dPsi.

0db76083ec fPsi no longer allocates memory
I noticed that phy2logquad had a lot of overhead. Trying to reducing it
by simplifying calls to fPsi, dPsi and such.

The function for fPsi has been made so no memory is allocated and works
under the assumption that the input array has the right size (1:numNodes)

23e2fe9bae I'm dying with hay fever but I have to commit
I'm feeling awful but I have work in my desktop that I need to commit so
I can work with my laptop while I'm at the IEPC 2022 in Boston.

cbb5fe0bf2 Merge branch 'feature/collisionPairs' into feature/electromagnetic
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.

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.

78a97ed7a0 Improve to collisions
Improvement into the collision model to better compute number of
particles collisions.

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.

9af3429395 Issue with random position in volumes
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.

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
c236c5e0e2 Fixing some issues in 3D Cartesian coordinates. Included 3D pusher.
Still there are issues linking a volume to an edge.

7e5b78f72f Implementation of 3D cartesian coordinates completed. Last commit before
testing.

ff0c09242d Fixed an issue with normal vector not being norm unit, which was causing
reflected particle velocities to increase.
2021-03-11 12:56:15 +01:00
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.
