#Description
This code calculates the excitation, heating and transport of free-carriers (electrons and holes, separately) of silicon irradiated by a laser pulse. The coupling with phonons and their diffusive transport is also calculated in time and space. Geometry is expressed in cartesian plane (x,y) and assumes invariance per translation. 

#Features
* The shape of the sample can be changed using a parametric function for the contour. 
* Equations are discretized using a *finite volume formulation* with mesh-free formulation.
* Calculations are performed in the (x,y) plane, thus assuming the invariance by translation on Z axis. This hypothesis was required since laser does not originates from the tip symmetry axis, but from aside.
* The Mie scattering theory for cylinders is locally applied for irradiations by the apex side. 
* The Fermi-Dirac statistics of electrons and holes are taken into account as a function of carrier density and temperature.

# Performances #

* CPU index (see column 10 in TimeMax.dat output file) of 3 is very good, for a mesh of 2000x150 cells. 

* CPU index of 60 is very good for a mesh of 150x150 cells.
