Guys, I'm used to create cylinder cellZones (for instance to use a rotorDisk model) directly into snappy as:

cylinder
{
  level           (1 2);
  faceZone        fz_cyl;
  cellZone        cz_cyl;
  cellZoneInside  inside;
}

Now, does anyone do it with faceZones only? I want to create a disk as a faceZone but I can't get snappy to snap onto the disk edge. I tried to change the faceType but without success
