+===== 0D Meshers (Points) ======
+===== Introduction =====
+{{:doc:user:ico-advanced.png?40 |Advanced}}
+In most cases, it is not necessary to mesh 0D entites (points). Such a mesh point is automatically generated when a line which includes it on one extremity is [[doc:user:geometry:mesh:1d|meshed]]. If the point must be meshed on its own, for example when the point is the reference point of a string, it is done with the command:
+  point.mesh()
+===== 0D Mesh =====
+==== Manually ====
+To create a 0D mesh element on a mesh point:
+  mesh.define(no, CELL_POINT, grp, no1)
+where
+| ''no''  | mesh number ((not used, in practice the mesh element is represented by the point itself and has the same number (''no1'') )) |
+| ''grp'' | entity which contains the mesh (a ''[[doc:user:geometry:user:selections|Group]]'' for example)|
+| ''no1'' | number of the mesh point|
+==== Automatically: CellPointMesher ====
+''CellPointMesher'' is a mesher which generates objects of type ''CELL_POINT'' in the topology, based on meshed geometric entities (which contains some ''MeshedPoints'').
+Le père de la maille est mis sur l'entité passée au ''CellPointMesher''  (pour le ''FieldApplicator''). :?:
+__Example:__
+Generation of a ''CELL_POINT'' on a ''[[doc:user:geometry:user:selections|Group]]' of mesh points, which come from a [[doc:user:geometry:import:tuto2|Bacon import]] for example.
+  mesher = CellPointMesher(groupset(no))
+  mesher.execute()
