    Hi all,

    In the openLB, is there a RotatingLinear2D functor? If not, how can I add this to the OpenLB?

    Hi lbmcoding,

    you can extend the source code by your functor. I recomment to copy an existing similar one. You are also welcome to email as the code to include in the next version of OpenLB.

    Dear mathias,
    Thanks for your reply. I have another question. When I handle a pipe flow simulation referring to the aorta3d examples, I found
    that in my simulation, “regionName=inflow; regionSize[m^2]=0”, “regionName=outflow; regionSize[m^2]=0” why does this happen? Are the coordinates of inflow and outflow circle incorrect? Thanks very much!

    It looks like they are incorrect!

    Dear mathias,
    Should I get their coordinates in the modeling software? As a general rule, how do we get this two coordinates?
    And the normal vector should orientate the external geometry?Thanks!!

    These parameteres depend on your actual geometry, so they come from outside!
