Class
    Foam::extrudePatchMesh

Description
    Mesh at a patch created on the fly. The following entry should be used
    on the field boundary dictionary:

    Example:
    \verbatim
        // New Shell mesh data

        extrudeModel    linearNormal;
        linearNormalCoeffs
        {
            thickness       40e-6;
        }
        nLayers         50;
        expansionRatio  1;
        columnCells      true;

        // Optional feature angle to avoid extruding feature-angles
        featureAngle    45;

        // Patch information
        bottomCoeffs
        {
            name        "bottom";
            type        mappedWall;
            sampleMode  nearestPatchFace;
            samplePatch fixedWalls;
            offsetMode  uniform;
            offset      (0 0 0);
        }

        topCoeffs
        {
            name        "top";
            type        patch;
        }

        sideCoeffs
        {
            name        "side";
            type        empty;
        }
