SYMMETRYFACE
(optional) definition of the geometry part as symmetryface (influences distance computation)
MESHFREE computes distances for points of the pointcloud to all SYMMETRYFACEs in proximity. The point is only considered to be inside if this it is inside regarding all different SYMMETRYFACEs.
Example:
begin_alias{}
"car" = " BC$...$ ACTIVE$...$ IDENT%...% MAT$...$ TOUCH%...% MOVE$...$ CHAMBER1 SYMMETRYFACE1"
"box" = " BC$...$ ACTIVE$...$ IDENT%...% MAT$...$ TOUCH%...% MOVE$...$ CHAMBER1 SYMMETRYFACE2"
end_alias
NOTE: The symmetryfaceByCluster overwrites the manually assigned SYMMETRYFACEs.
NEW TEMPORARY ITEM
If defining a negative number such as "SYMMETRYFACE-2", then this partition of the boundary does not take part in the filling of interior points,
that is, the points on this partition of boundary cannot act as sources for new INTERIOR points. Of course, they can act as sources for new points on
the geometry partition itself.
This functionality is temporary, as it was easy to implement it in this way. A more consistent solution will follow.
