i :=,iside,s<,slot>)


  • 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)

Removes the group name s from the face identified by z and iside in any slot where it is found. The removal of s will only occur in slot, if provided. The return value is 0 if the specified group is not assigned to that face.


i - 0 if the group is not found, nonzero otherwise


z - zone pointer

iside - index of the zone face, from 1 to 4 in 2D and from 1 to 6 in 3D

s - group name or index*

slot - slot name or index


*Use the group.find and group.find.slot intrinsics to obtain group and slot indices, respectively, and for further information.

Use of the group logic is described in Groups.
