DESCRIPTION
___________

Computes the friction velocity at the wall for laminar flow

      UET = SQRT (TAU/RO) = SQRT (NU*dV/dY)

with ; TAU  shear stress
       RO   density
       NU   cinematic viscosity
       V    velocity component parallel to the wall
       Y    distance from the wall

UET    friction velocity (m/s)          CHPOINT SCAL CENTRE WALL

NU     cinematic viscosity (m2/s)       FLOTTANT

UN     velocity field (m/s)             CHPOINT VECT SOMMET DOMT

NOR    normal to the faces field (m)    CHPOINT VECT FACE DOMT

$DOMT  total field                      MMODEL TYPE 'NAVIER_STOKES'


$WALL  wall line (2D)                   MMODEL TYPE 'NAVIER_STOKES'




Remarks :
_________

- NOR is computed by the DOMA operator over the whole domain
               ('NORMALE' option)
- The KUET operator only works in 2D (plan or axially symetric)
