Distinction
Topology optimization is distinct from shape optimization since typically shape optimisation methods work in a subset of allowable shapes which have fixed topological properties, such as having a fixed number of holes in them. Therefore topology optimisation is used to generate concepts and shape optimisation is used to fine-tune a chosen design topology.
There are various methods used to perform topology optimisation:
- Solid Isotropic Material with Penalisation (SIMP),
- Evolutionary Structural Optimisation (ESO),
- Topological derivatives.

Famous quotes containing the word distinction:
“This is no rune nor symbol,
what I mean is it is so simple
yet no trick of the pen or brush
could capture that impression;
what I wanted to indicate was
a new phase, a new distinction of colour.”
—Hilda Doolittle (1886–1961)
“A distinction of property results from that very protection which a free Government gives to unequal faculties of acquiring it.”
—James Madison (1751–1836)
“The distinction between children and adults, while probably useful for some purposes, is at bottom a specious one, I feel. There are only individual egos, crazy for love.”
—Don Barthelme (1931–1989)
