\section combining_filters How to combine filters with Criterion structures?
Filters can be combined by making use of "criteria".
Example :
\code
# create mesh
from SMESH_mechanic import *
# get all the quadrangle faces ...
criterion1 = smesh.GetCriterion(smesh.FACE, smesh.FT_ElemGeomType, smesh.Geom_QUADRANGLE, smesh.FT_LogicalAND)
# ... AND do NOT get those from sub_face3
criterion2 = smesh.GetCriterion(smesh.FACE, smesh.FT_BelongToGeom, sub_face3, smesh.FT_LogicalNOT)
filter = smesh.CreateFilterManager().CreateFilter()
filter.SetCriteria([criterion1,criterion2])
ids = mesh.GetIdsFromFilter(filter)
myGroup = mesh.MakeGroupByIds("Quads_on_cylindrical_faces",smesh.FACE,ids)
\endcode
