+     * 0 : The time step is constant and defined by the user by means of the variable "Timestep_max" (see further).
+     * -1 : The time step evolves lineraly between the values given by "Timestep_min" and "Timestep_max". The range of variation is defined by the variable "Iterations_For_Timestep_Linear_Progress" (in time iteration number).
+     * 1 : The time step is calculated for each time iteration by means of the CFL parameter. The CFL parameter can be constant, it is thus defined by the variable "CFL_Max".\\ It can also evolve linearly between the values given by  "CFL_Min" and "CFL_Max" and the variable "the varievolves linearly between the values "Timestep_min" and "Timestep_max". The range of variation is defined by the variable "Iterations_For_Timestep_Linear_Progress" (in time iteration number).
