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.
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().
Now collisions can have a different time step.
Added species name to output names as it was starting to get confusing
in Gmsh for multiple species.
Output filenames adapted to match any number of iterations.
