Class
    Foam::regionModels::surfaceFilmModels::
        perturbedTemperatureDependentContactAngleForce

Description
    Temperature dependent contact angle force with a stochastic perturbation

    The contact angle in degrees is specified as a Foam::Function1 type, to
    enable the use of, e.g.  contant, polynomial, table values and the
    stochastic perturbation obtained from a
    Foam::distributionModels::distributionModel
