Description
    Set of surfaces to sample
 
    Example of function object specification:
    \verbatim
    surfaces1
    {
        type            surfaces;
        libs            ("libsampling.so");
 
        writeControl    writeTime;
 
        fields          (p U);
 
        surfaceFormat   vtk;
        interpolationScheme cellPoint;
 
        surfaces
        (
            p1e5
            {
                type            isoSurface;
                isoField        p;
                isoValue        1e5;
                interpolate     yes;
            }
        );
    }
    \endverbatim
 
Usage
    \table
        Property     | Description             | Required    | Default value
        type         | type name: surfaces     | yes         |
        surfaceFormat | the format in which to write the surface file | yes   |
        interpolationScheme | the method by which values are interpolated \\
                              from the mesh to the surface | yes
        writeEmpty   | write out files for empty surfaces | no | no
        surfaces     | the list of surfaces    | yes         |
