The manual has been modified to account for the new particlePerEdge
option and to indicate that now when the flux is giving by a flux like
in the Am2 units, the real surface of the inject is used to scale it.
The number of particles per cell can be defined when giving an initial
distribution fora species. If not, the typical method of using the
species weight is used. This is particularly useful for cylindrical
coordinates in which very little particles might end up in the axis if a
constant weight is used.
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.
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.
