    Hello everyone,
    In the examples of free energy model, by what methodology are the multi-phase parameters (alpha, kappa, gama and h) typically established

    Hello Bobbie,

    for this question I would like to refer to the LBM literature that deals with Cahn-Hilliard multiphase models. Alpha and Kappa are important for free energy and surface tension, gama is used to adjust the CHE mobility and h is used for setting contact angles.

    Hope this helps,
    Best regards
    Tim
