35 * \brief Hypothesis for StdMeshers_Regular_1D, forcing construction of quadratic edges.
36 * If the 2D mesher sees that all boundary edges are quadratic ones,
37 * it generates quadratic faces, else it generates linear faces using
38 * medium nodes as if they were vertex ones.
39 * The 3D mesher generates quadratic volumes only if all boundary faces
40 * are quadratic ones, else it fails.
