!> \file predvv.f90
!>
!> \brief This subroutine performs the velocity prediction step of the Navier
!> Stokes equations for incompressible or slightly compressible flows for
!> the coupled velocity components solver.
!>
!> - at the first call, the predicted velocities are computed and also
!> an estimator on the predicted velocity is computed.
!>
!> - at the second call, a global estimator on Navier Stokes is computed.
!> This second call is done after the correction step (\ref resopv).
