j := zone.join(z,i)


  • In the description below, the following correspondence is assumed between 3D and 2D analysis:
    • 3D zone faces (surfaces) <-> 2D zone edges (lines)

Get the zone joined to face i of zone z. This will return null if there is no zone connected to that face. Note that the connection must be topologically perfect.


j - the zone across the face, or null if non exists


z - a pointer to a zone

i - the face number of the zone being checked. This is a number from 1 to 6 for hexahedral zones and from 1 to 4 for quadrilateral zones. If the face does not exist for other zone types, null will always be returned.
