WebA fixed point is a zero-dimensional geometry entity that is associated with a surface. It is displayed as a small "o", and its color is determined by the surface to which it is associated. The automesher places a node at each fixed point on the surface being meshed.

If disturbances are introduced to a system at steady state, two different results may occur: the system goes back to … In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre-fixpoint) of f is any p such that f(p) ≤ p. Analogously, a postfixed point of f is any p such that p ≤ f(p). The opposite usage occasionally appears. Malkis justifies the definition presented here as follows: "since f is before …
