Dear all,

           I use Nektar++ mainly to study time dependent 3D plane Poiseuille flow, using  the Incompressible Navier-Stokes Solver (using a fully 3D configuration),
I'm wondering what would be the best approach to add Blowin and/or Suction at the wall ?
Looking into the user-guide version 5.1.0 section 3.5.1- XML-Session-File>Forcing>Absorption seems to be a usable feature in this context
Is there an efficient and suitable approach to add these perturbations to the flow ?

           Any general guidelines to achieve this are really appreciated,

Thanks in advance,

Kind regards,

Saad
