Abstract
Methods, systems, and apparatus, including medium-encoded computer program products, for designing and manufacturing physical objects including lattice structures include, in one aspect, a method including: providing a three-dimensional model including a dual representation of a lattice structure, wherein both a shell mesh model and a solid body model of the lattice structure are producible from an additional model of the lattice structure, and beams of the lattice structure in the solid body model are hollow; performing numerical simulation using at least the shell mesh model of the dual representation to produce a current numerical assessment; modifying the additional model of the dual representation based on the current numerical assessment; 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 for use in manufacturing the lattice structure.
