+\tableofcontents

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 use the functionality of mesh quality controls to filter
mesh nodes / elements by a specific characteristic (Area, Length, etc).

+- element type can be any entity type, from \a SMESH.NODE to \a SMESH.VOLUME
+- functor type should be \a SMESH.FT_BelongToMeshGroup
