Could we get composites, visco-elastic, and other advanced materials for simulation?
For composites; being able to dictate fiber orientations and ply thicknesses would be really helpful. Not to mention put it well beyond most other solid modeling software out there. What I imagine would be declaring that particular faces or components have 100% fibers divided into different directions (for instance 50% i, 25%j, 25%k). This of course doesn't work very well for molded and organic shapes, but in that case the assumption that the fibers follow the i, j, k percentages while remaining parallel and coincident with the organic surface direction might suffice. It would also be helpful to be able to dictate filament and matrix for the material. Carbon-Fiber, Glass-Fiber, Nano-Tube, etc combined with different epoxy matrix types would allow for a more complete engineering solution I think.
In similar fashion; having access to non-linear visco-elastic materials would be a pretty amazing addition to the simulation library. Rubbers that deform non-linearly or polymers that have accurately modeled ultimate compression strength (there's some that actually have no ultimate compression strength).
This things would add additional depth and functionality to an already robust system.
