zone.face.isgroup
Syntax
- b := zone.face.isgroup(z,iside,s<,slot>)
Note
- In the description below, the following correspondence is assumed between 3D and 2D analysis:
There is no 2D equivalence for 3D zone edges
3D zone faces (surfaces) <-> 2D zone edges (lines)
Check if the group name s is associated with the zone face indicated by z and iside and return true if a match is found in any slot. The check for s will only occur in slot, if provided.
Note that this function will return a match if any zone attached to the face contains that group name, as well as the face itself.
A group index or slot index may be used for the arguments s or slot, respectively. Indices operate more efficiently than strings*.
- Returns:
- Arguments:
z - zone pointer
iside - side of the zone indicating the face, from 1 to 4 in 2D and from 1 to 6 in 3D
s - group name or index*
slot - slot name or index*
Note
*Use the
group.find
andgroup.find.slot
intrinsics to obtain group and slot indices, respectively, and for further information.Use of the group logic is described in i Groups.
