\n This algorithm applies to the meshing of 2D shapes under the
-following conditions: the face must be a full circle or a part of circle
-(i.e. the number of edges is less or equal to 3 and one of them is a circle curve).
+following conditions: the face must be a full ellipse or a part of ellipse
+(i.e. the number of edges is less or equal to 3 and one of them is an ellipse curve).
The resulting mesh consists of triangles (near the center point) and
quadrangles.
-This algorithm is optionally parametrized by the hypothesis indicating the number
-of mesh layers along the radius. The distribution of layers can be set with any 1D Hypothesis.
+This algorithm is optionally parametrized by the hypothesis indicating

+can be set with any 1D Hypothesis. If the face boundary includes
+radial edges, this distribution is applied to the longest radial
+edge. If the face boundary does not include radial edges, this
+distribution is applied to the longest virtual radial edge. The
+distribution is applied to the longest radial edge starting from its
+end lying on the elliptic curve.
-If no own hypothesis of the algorithm is assigned, any local or global hypothesis is used
-by the algorithm to discretize edges. Note that if the geometrical face has two radial edges,
-they must be meshed with equal number of segments.
-If no 1D hypothesis is assigned to an edge, "Default Number of Segments" preferences parameter
-is used to discretize the edge.
