===== 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()
