4 Simulation-driven biomimetic design One of the first drivers of the concepts behind simulation-driven design was from the ideas of Julius Wolff , the 19th Century Orthopedic surgeon , who first suggested that , a consequence of primary shape variations and continuous loading , or even due to loading alone , bone changes its inner architecture according to mathematical rules and , as a secondary effect and governed by the same mathematical rules , also changes its shape .
