Synthesizing Structure & Chaos

That certainly is an apt metaphor for CFD mesh generation: providing a synthetic structure on which the chaos of turbulent fluid motion is to be computed.

Don Sorenson, Untitled #19, 1974

From his website, artist Don Sorenson‘s work is described thusly:

“Formally, his paintings are amalgams of the polar opposites with which large stylistic swings in the history of art have been described: intellect and emotion, order and randomness, control and accident, structure and chaos, straight line and amorphous color, gloss and matte, literal flatness and illusionistic depth, figure and ground and so forth. It is through a synthesis of art history that Sorenson finds his unique place in the world of contemporary art.”
