zone.face.gp

Syntax

gp := zone.face.gp(z,iside<,ivertex>)

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)

Get a pointer to a gridpoint on face given by zone z, iside, and ivertex, as described in Orientation of Nodes and Faces within a Zone.

If the vertex argument is not provided, then a list of all gridpoints associated with the face is returned.

Returns:

gp - a pointer to a gridpoint, or a list of all gridpoints associated with the face

Arguments:

z - a pointer to a zone

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

ivertex - the face vertex index, from 1 to 2 in 2D and from 1 to 4 in 3D
