    When I plotted the graph of Cylinder3d by a line at z-axis at the inlet, the graph creats two humps in the begainning and at the end of the of the line but as compared to the ansys counterpart model that is uniform at both ends. Tell me the reason behind it and which part of the code is creating the humps or what is the solution for it so that I can remove the humps? Please reply. There is no major changes done in the OpenLB code.

    Are you talking about the converged state? I cant see them. Do you also see them if using

    setLocalVelocityBoundary(sLattice, omega, superGeometry, 3);

    instead of

    setInterpolatedVelocityBoundary(sLattice, omega, superGeometry, 3);

    ?
