Hanging nodes are created during grid adaption in FLUENT. You can't create hanging nodes in GAMBIT.

Hanging nodes: when you need to refine an area of a mesh due to lack of detail in your solution (BL maybe), for each face within selected region, a node is imposed in the centre, thus dividing the cell face into four. This node is known as a "hanging node". It is a method of selective refining, and is usually applied to cells of certain gradient (y+ for example).

I have a different understanding of what a hanging node is.
before refinement (two cells) *-----------*-----------* : : : : : : : : : : : : : : : *-----------*-----------* after refinement (5 cells) *-----------*-----*-----* : : : : : : : : : a-----b-----* : : : : : : : : *-----------*-----*-----* In my understanding, a is a hanging node, and b isn't.
