1. A method comprising:
providing a three-dimensional model of a physical object to be manufactured, wherein the three-dimensional model comprises a dual representation of a lattice structure of the physical object, the dual representation comprising (i) a shell mesh model of the lattice structure and (ii) an additional model of the lattice structure, wherein both the shell mesh model and a solid body model of the lattice structure are producible from the additional model, and beams of the lattice structure in the solid body model are hollow;
performing numerical simulation using at least the shell mesh model to produce a current numerical assessment;
modifying the additional model of the lattice structure based on the current numerical assessment to change the lattice structure and update the shell mesh model;
repeating the performing and the modifying one or more times until the numerical simulation indicates the lattice structure satisfies at least one response requirement; and
providing at least the solid body model, produced from the additional model, for use in manufacturing the lattice structure of the physical object using one or more computer-controlled manufacturing systems.
