    Dear Administrator,
    I’m currently running multicomponent2D & 3D model from openLB. The geometry is defined in terms of nx, ny and nz. Since there is no LBConverter in that code, I’m not able to figure it out. can you please provide me what are the units for them?

    If I need to change the properties of fluid then how can I make the changes?

    thanks.

    Dear bujji,

    the values nx denotes the number of cells in x direction.

    Dear Albert,
    thanks for the quick reply.

    how can we find its physical units & fluid properties?

    Can you tell me which specific physical units you are looking for?

    From my developper point of view, I need a hint from your side.

    lattice size in terms of SI units,
    Fluid properties like density and surface tension.

    thanks

    Well, the code provides only lattice units, see force and omega1 resp omega2. At that point we do not relate those values to physical units.
    Feel free to participate to OpenLB and provide physical related version of multicomponent2D.
    In fact we prepare a new LBconverter for the upcoming release of OpenLB.
