Abstract: Systems and methods for optimizing a lattice structure design are disclosed herein. In some embodiments, a method for optimizing a lattice structure design can include (i) modeling the lattice structure with a component-wise reduced-order model (CWROM) and (ii) optimizing the CWROM based on a selected criterion using a topology optimization algorithm for lattice design. The selected criterion can include a boundary condition and a load applied to the lattice structure. By modeling the lattice structure as a CWROM, the optimization process can be very fast while still permitting the accurate computation of physical quantities of the lattice structure.

Abstract: A design engine for designing an object using structural analysis. The design engine generates a lattice structure for the object comprising a plurality of nodes and a plurality of lines connecting the nodes. The lattice structure is optimized to remove one or more lines using structural analysis based on at least one load-related design requirement. Several design options are provided for generating and optimizing the lattice structure. The design engine then generates a 3D model of the object by thickening each line of the lattice structure into a pipe volume. The thickness of each pipe is determined using structural analysis based on the at least one load-related design requirement. The 3D model represents the volume of the object and is exportable to a fabrication device.

Abstract: Techniques for determining simulations to confirm programmatic logic are discussed herein. Such simulations may be used to identify errors in programmatic logic. As an example, a system may simulate an autonomous vehicle operating in an environment by setting various initialization parameters. Temporal logic, such as Linear Temporal Logic (LTL) and/or Signal Temporal Logic (STL) may be used to determine a numeric cost associated with how closely one or more policies are violated for each simulation of a group of simulations. Based on the costs computed, additional sets of simulations may be created using an evolutionary algorithm. Flaws in programmatic logic controlling the system may be identified based on the evolutionary algorithms and cost defined.

Abstract: Improved CAD systems provide automatic generation of simplified and defeatured versions of complex 3D CAD models. The systems receive a 3D model representing a real-world object as an assembly. The model is formed of the assembly, plural components, and features. In response to user command, the systems select one or more components of the plural components. The systems apply a simplification operation to the selected one or more components. The simplification operation derives a simplified geometric entity (e.g., box, cylinder, solid 3D polygonal outline, or solid 3D tight fit outline) by projecting at least one silhouette outline that encloses the selected one or more components. The at least one projected silhouette outline excludes features of the selected one or more components from graphical view. The systems generate a simplified model from the derived simplified geometric entity. The systems may use the generated simplified model to replace components in 3D models.
