    Hi,

    I want to apply the ZouHe velocity boundary at the walls in the poiseuille2d program provided by the openlb. But I could not find where to make changes in the existing program. Can anybody please guide me?

    Hi rajatzope,

    to change the type of the boundary implementation you just need to replace one line. Currently (depending on your setup)
    createInterpBoundaryCondition2D or createLocalBoundaryCondition2D
    are used, just need to replace the line with
    createZouHeboundaryCondition

    Best
