[Nek5000-users] Laminar Flow Poiseuille

[nek5000-users at lists.mcs.anl.gov]

Ok, if you are looking for plane-poiseuille flow you can look into the
turbChannel example. It is designed for turbulent channel flow, but you can
reduce the Reynolds number to generate a desired 3D Laminar flow. Also it
is periodic boundary conditions, you can modify BC's like inflow/outflow
according to your wish.
