    Dear OpenLB community,

    When the particle is in motion, and and I apply periodic boundary conditions on the left and right, why the the other side of the domain is not effected. Please refer to the figure:

    This also happens with pressure but not temperature.


    Dear Henderson,

    Unfortunately, I can’t provide you with a solution to the above problem because I don’t know your simulation setup. Here are a few things you might check:
    – Is the periodic boundary applied correctly?
    – Maybe also check the “geometry” in ParaView, in the direction of the periodic boundary the material should most likely be 1
    – Compare your implementation with examples that use a periodic setup, e.g. Poiseuille2d, are there any differences?

    For extensive help with your setup I suggest the Spring School:

    Best regards,
