Class
    Foam::DimensionedFieldFunctions::Surfaces
 
Description
    Dimensioned field function which sets constant values inside a set of
    surfaces, and a default value elsewhere. Cutting is used to set fractional
    values in elements that intersect the surfaces. Foam::searchableSurface is
    used to define the surface geometry, so triangulated surface files can be
    used, as well as a list of simple predefined shapes (box, cylinder, ...).
 
    Example specification:
    internalField
    {
        type        surfaces;
 
        // Set a value of one everywhere, except ...
        defaultValue 1;
 
        surfaces
        {
            // Set a value of zero in a sphere
            bubble
            {
                type        sphere;
 
                centre      (0.5 0.5 0.5);
                radius      0.1;
 
                value       0;
            }
 
            // Set a value of zero where the y coordinate is greater than 1
            air
            {
                type        plane;
 
                point       (0 1 0);
                normal      (0 -1 0);
 
                value       0;
            }
        }
    }
