2 Synopsis


3 Description

Utility to split cells with flat faces. EDGEANGLE is expressed in degrees and takes a value in [0..360]

Uses a geometric cut with a plane dividing the edge angle into two so might produce funny cells. For hexes it will use by default a cut from edge onto opposite edge (i.e. purely topological).


  • split cells from cellSet only
  • use geometric cut for hexes as well

The angle is the angle between two faces sharing an edge as seen from inside each cell. So a cube will have all angles 90. If you want to split cells with cell centre outside use e.g. angle 200


Use geometric cut for hexes as well
