    Dear all,
    In the example given for poiseuille 2d flow. Periodic Boundary Condition is used in horizontal direction (inlet and outlet) and No-slip is used in both the upper and lower walls of the channel.

    On the corners (all four corners of the channel) do we use both the boundary conditions or any-one of them?

    Thanking you.

    Regards

    In the corners we have chosen also no-slip. You can check that by opening the geometry vtk file and look at the material numbers.

    Thank you Mathias for your response!
    Can you please give me some idea on how to deal with corners. If I use any of the two available boundary conditions like here in this case you used No-Slip and avoided using PBC. Results should not be significantly different if my system size is large enough?
    Thanks a lot.

    I would do it as I have propsed before. You can see it in the example and will will see there that is works fine!
