Class
    Foam::temperatureDependentAlphaContactAngleFvPatchScalarField

Description
    Temperature-dependent alphaContactAngle scalar boundary condition.

    The contact angle is evaluated from the specified Foam::Function1 for the
    temperature field looked-up from the mesh database the name of which
    may optionally be provided.

Usage
    \table
        Property     | Description             | Required    | Default value
        T            | Temperature field name  | no          | T
        theta0       | Contact angle function  | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            temperatureDependentAlphaContactAngle;
        theta0          constant 60;
    }
    \endverbatim
