Class
    Foam::filmContactAngleFvPatchScalarField
 
Description
    Film contact angle boundary condition.
 
Usage
    Examples of the contact angle specification:
 
    Simple constant equilibrium contact angle:
    \verbatim
    <patchName>
    {
        type            filmContactAngle;
 
        contactAngle
        {
            type                constant;
            theta0              70;
        }
    }
    \endverbatim
 
    Same as above but using the simpler specification:
    \verbatim
    <patchName>
    {
        type            filmContactAngle;
 
        theta0          70;
    }
    \endverbatim
 
    Dynamic contact angle evaluated from the velocity:
    \verbatim
    <patchName>
    {
        type            filmContactAngle;
 
        contactAngle
        {
            type           dynamic;
            uTheta         1;
            theta0         70;
            thetaAdv       100;
            thetaRec       50;
        }
    }
    \endverbatim
