Radial Quadrangle 1D-2D
|
|
***********************
|
|
|
|
This algorithm applies to the meshing of 2D shapes under the
|
|
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. 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.
|
|
|
|
If no 1D hypothesis is assigned to an edge,
|
|
:ref:`Default Number of Segments <nb_segments_pref>` preferences
|
|
parameter is used to discretize the edge.
