FLUENT 5 - Meshing Algorithm to mitigate right triangles (or cut squares) in Hypermesh surface mesh.
Hypermesh surfaces meshes have a tendency to be rectangles divided up into triangles. If the quadrilaterals are actually squares, the resulting surface mesh can create problems for volume meshing in TGrid. Triangles created by cutting a square into two are a violation of the Delauney Condition.
To mitigate the creation of triangular surfaces that are
squares cut along the diagonal. (As seen in Hypermesh v4.0.2-2)

Autodecide: will likely give you the right angle triangles
Free (unmapped): will mitigate their creation.
I do not know if there is a large change in number of elements
between the two algorithms. One client said they were similar in
