    Hi everyone,
    In the example of cylinder3d,the outflow boundary is
    ‘setInterpolatedPressureBoundary<T,DESCRIPTOR>(sLattice, omega, superGeometry, 4)’,but I want to use the free-outflow boundary condition.I want to ask how to set free-outflow boundary condition in the outflow.I am looking forward to your apply.
    Yours sincerely,
    Xu Yang.

    Dear Xu Yang,

    i would suggest to try the setZeroDistributionBoundary which sets every population with direction into the bulk to zero.
    I hope this fits to your application case.

    Yours sincerely,
    Johanna
