Filters allow picking only the mesh elements satisfying to a
specific condition or a set of conditions. Filters can be used to create
or edit mesh groups, remove elements from the mesh object, control
mesh quality by different parameters, etc.
-Several filters can be combined together by using logical operators \a
-AND and \a OR. In addition, applied filter criterion can be reverted
-using logical operator \a NOT.

+Mesh filters can use the functionality of mesh quality controls to filter
mesh nodes / elements by a specific characteristic (Area, Length, etc).
This page provides a short description of the existing mesh filters,
\section filter_double_elements Double edges, Double faces, Double volumes
filter mesh elements basing on the same set of nodes:
-- element type is either \a smesh.EGDE, \a SMESH.FACE or \a SMESH.VOLUME
+- element type is either \a SMESH.EGDE, \a SMESH.FACE or \a SMESH.VOLUME
- functor type is either \a SMESH.FT_EqualEdges, \a
SMESH.FT_EqualFaces or \a SMESH.FT_EqualVolumes,
- threshold value is not required
\sa \ref tui_over_constrained_faces
+\section filter_belong_to_group Belong to Mesh Group
+
+Filter mesh entities (nodes or elements) included in a mesh group
+defined by threshold value:
+- element type can be any entity type, from \a SMESH.NODE to \a SMESH.VOLUME
+- functor type should be \a SMESH.FT_BelongToMeshGroup
+- threshold is mesh group object
