Hi Foamers,

I need a clarification regarding slip velocity in porous zone in openFoam/tutorial/incompressible/porousSimpleFoam/angledDuctExplict.

In 0/U boundary condition for poroistyWall is given as "slip" and at other Wall "noSlip"

I have simple 2D channel flow with a porous blockage in the middle as shown below.The porous square cylinder is fully surrounded by free fluid.

Do i need to define "slip velocity at cylinder Walls"

Help needed to define boundary conditions for porous cylindercfd.png
