The Poisson equation was not working because I didn't finish
implementing the new type of BCs. Dirichlet is probably untested. I
should stop doing shitty developments and no testing.
I should've commited before, but I wanted to make things compile.
The big change is that I've added a global time step so the parameter
does not need to be passed in each function. This is useful as we are
moving towards using time profiles for boundary conditions and injection
of particles (not in this branch, but in the future and the procedure
will be quite similar)
Planning the new way to do BC in the EM field solver.
Probably I have to change how things are read, but I don't think this is
going to affect the input file.
Just some comments on how I am going to make the desired changes (have a
Dirichlet boundary condition for the electric potential that changes
with time). This might be a good opportunity to rework the boundary
conditions in the electrostatic field and include other things like a
Newmann boundary condition. We will see.
WARNING: This current denstiy will be multiplied by the reference
length, no the surface area that is being used for injection!
New units in the injection of particles 'Am2' to inject a density
current. Manual has been modified accordingly.
Reference parameters are now also printed in the case folder.
When the relative velocity between a charged particle and the background
for Coulomb collisions (W in the code) was low, there was a
segmentation fault. This is fixed now as if the norm of the relative
velocity (normW) in the code is too low, no collision is applied.
First attemp for Coulomb collisions based on the moments distribtuions.
Still the method is not done and far from being complete but input
options and basic math are implemented.
During the improve performant step, an error in the electrostatic
pushers was introduced, resulting in these using the minimum time step
and not the species time step when calculating the acceleration.
Now particles can be split to increase statistics when they enter a
smaller cell. However, this only has an effect for collisions.
Still, I have to rethink a lot about this feature.
