Neat exercise. Computational design and merging with ID are always interesting since it addresses a specific piece of the design criteria (in this case drop/tumble), but areas which may be subjective (grip, aesthetics, ease of installation, manufacturability) are ultimately left out of the equation.
The auto industry seems to be using a lot of computational design and FEA work to better inform how they can build the strongest parts for the minimal amount of cost/material. You see this a lot for things like suspension arms, crumple zones and other structural components where the strongest, lightest and stiffest part is ideal.
Would be interesting to see the same approach taken for something more organic like a bike helmet.
