!> - icp = 1 must <b> have been specified </b>

!> \remarks
!> - This routine is called at the beginning of each time step
!> Thus, <b> AT THE FIRST TIME STEP </b> (non-restart case), the only
!> values initialized before this call are those defined
!> - in the GUI or \ref usipsu (cs_user_parameters.f90)

!> - in the GUI or \ref cs_user_initialization
!> - calculation variables (initialized at 0 by defaut
!> or to the value given in the GUI or in \ref cs_user_initialization)
!>
!> - We may define here variation laws for cell properties, for:
!> - density: rom kg/m3
!> - density at boundary faces: romb kg/m3)
!> - molecular viscosity: cpro_viscl kg/(m s)
!> - specific heat: cpro_cp J/(kg degrees)
!> - diffusivities associated with scalars: cpro_vscalt kg/(m s)
!>
!> \b Warning: if the scalar is the temperature, cpro_vscalt corresponds

!>
!>
!> The types of boundary faces at the previous time step are available
