zone.face.find

Syntax

i := zone.face.find(z,gp1,gp2) (FLAC2D)

i := zone.face.find(z,gp1,gp2,gp3) (FLAC3D)

Note

• In the description below, the following correspondence is assumed between 3D and 2D analysis:

  • 3D zone faces (surfaces) <-> 2D zone edges (lines)

In FLAC2D, get the face index of zone z that contains the two gridpoints gp1, gp2.

In FLAC3D, get the face index of zone z that contains the three gridpoints gp1, gp2, and gp3.

Each gridpoint may be specified by pointer or by ID number. If no face is found, −1 is returned.

Returns:

i - the index of the matching face (from 1 to 4 in 2D, from 1 to 6 in 3D) or -1 if no match is found

Arguments:

z - a pointer to a zone

gp1 - either a pointer to a gridpoint or a gridpoint ID number

gp2 - either a pointer to a gridpoint or a gridpoint ID number

gp3 - either a pointer to a gridpoint or a gridpoint ID number (3D ONLY)
