! FONCTION :

! ROUTINE PHYSIQUE PARTICULIERE : REMPLISSAGE DES VARIABLES PHYSIQUES



! ATTENTION :
! =========


! Il est INTERDIT de modifier la viscosite turbulente VISCT ici
!        ========
!  (une routine specifique ppvist devra etre creee)


!  Il FAUT AVOIR PRECISE ICP(IPHAS) = 1
!     ==================
!    dans usini1 si on souhaite imposer une chaleur specifique
!    CP variable pour la phase IPHAS (sinon: ecrasement memoire).


!  Il FAUT AVOIR PRECISE IVISLS(Numero de scalaire) = 1
!     ==================
!     dans usini1 si on souhaite une diffusivite VISCLS variable
!     pour le scalaire considere (sinon: ecrasement memoire).




! Remarques :
! ---------

! Cette routine est appelee au debut de chaque pas de temps

!    Ainsi, AU PREMIER PAS DE TEMPS (calcul non suite), les seules
!    grandeurs initialisees avant appel sont celles donnees
!      - dans usini1 :
!             . la masse volumique (initialisee a RO0(IPHAS))
!             . la viscosite       (initialisee a VISCL0(IPHAS))
!      - dans usppiv :
!             . les variables de calcul  (initialisees a 0 par defaut
!             ou a la valeur donnee dans usiniv)

! On peut donner ici les lois de variation aux cellules
!     - de la masse volumique                      ROM    kg/m3
!         (et eventuellememt aux faces de bord     ROMB   kg/m3)
!     - de la viscosite moleculaire                VISCL  kg/(m s)
!     - de la chaleur specifique associee          CP     J/(kg degres)
!     - des "diffusivites" associees aux scalaires VISCLS kg/(m s)


! On dispose des types de faces de bord au pas de temps
!   precedent (sauf au premier pas de temps, ou les tableaux
!   ITYPFB et ITRIFB n'ont pas ete renseignes)
