After some testing and making things a bit better and more general, I am
quite happy with the implementation of vtu and it seems that it is
working (at least as good as Gmsh2).
There are some procedures that might be useful for other XML-like
formats that might be moved in the future to the common module (I am
thinking right now in the implementation of a general format like
XDMF3).
Now, if no normal is provided to an injection in the input file, the
velocity direction of the particles is chosen to be the surface normal.
This allows to inject particles from curves, corners... without having
to provide a direction or declaring multiple injections.
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.
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.
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.
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.
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.
directional derivative depending on the definition of first node. Trying
to solve it with searching for the right first node but it is very
difficult. A solution is required to allow triangular meshes in charged
simulations.
