-<h2>Quadrangle Preference</h2>
-
-This additional hypothesis can be used together with Quadrangle (Mapping) and Netgen 2D
-algorithms.
-
-It allows Netgen 2D to build quadrangular meshes at any conditions.
-
-It allows Quadrangle (Mapping) to build quadrangular meshes even if the number
-of nodes at the opposite edges of a meshed face is not equal,
-otherwise this mesh will contain some triangular elements. <i>This use
-case is obsolete now. Use <b>Quadrangle Parameters</b> hypothesis with
-type <b>Quadrangle Preference</b> set instead.</i>
-<br>
-This hypothesis has one restriction on its work: the total quantity of
-segments on all four sides of the face must be even (divisible by 2).
-
-<h2>Triangle Preference <i>(obsolete)</i></h2>
-
-This additional hypothesis can be used only together with Quadrangle (Mapping)
-algorithm. It allows to build triangular mesh faces in the refinement
-area if the number of nodes at the opposite edges of a meshed face is not equal,
-otherwise refinement area will contain some quadrangular elements.
-<i>This hypothesis is obsolete now. Use <b>Quadrangle Parameters</b>
-hypothesis with type <b>Triangle Preference</b> set instead.</i>
