Component-wise reduced-order model design optimization such as for lattice design optimization

One or more computing systems for optimizing a lattice structure design, the one or more computing systems comprising:

• one or more computer-readable storage mediums for storing computer-executable instructions for controlling the one or more computing systems to—
• generate a component-wise reduced-order model (CWROM) of a lattice structure;
• and
• optimize, based on a selected criterion, the CWROM using a topology optimization algorithm;
• and
• one or more processors for executing the computer-executable instructions stored in the one or more computer-readable storage mediums.

A method performed by one or more computing systems for optimizing a lattice structure design, the method comprising:

• modeling a plurality of micro-level lattice components as finely-discretized numerical meshes;
• generating a reduced-order model for each of the lattice components;
• generating a component-wise reduced-order model (CWROM) of a macro-level lattice structure from multiple ones of the reduced-order models for the lattice components;
• assigning a design variable to each of the lattice components in the lattice structure, wherein the design variable includes at least one of a density, a shape, and a position of the corresponding lattice component;
• and
• optimizing, based on a selected criterion, the design variable for each of the lattice components in the lattice structure.
