+Segments around Vertex
+**********************
+
+**Segments around Vertex** algorithm is considered to be a 0D meshing
+algorithm, but, of course, it doesn't mesh vertices. It allows to define
+the local size of the segments in the neighborhood of a certain
+vertex. If we assign this algorithm to a geometrical object of higher
+dimension, it applies to all its vertices.
+
+.. _note: To create 0D elements, use :ref:`adding_nodes_and_elements_page` operation.
+
+Length of segments near vertex is defined by **Length Near Vertex** hypothesis.
+This hypothesis is used by :ref:`Wire Discretization <a1d_algos_anchor>` or
+:ref:`Composite Side Discretization <a1d_algos_anchor>` algorithms as
+follows: a geometrical edge is discretized according to a 1D
+hypotheses and then nodes near vertices are modified to assure the
+segment length required by **Length Near Vertex** hypothesis.
