Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using generative design processes. A method includes obtaining one or more load cases and one or more design criteria for a modeled object; iteratively modifying a three dimensional shape of the modeled object in accordance with the one or more design criteria and the one or more load cases, the iteratively modifying comprising regulating shape change velocities for an implicit surface representation of the three dimensional shape that exceed a reference velocity, where the reference velocity is set based on a mean and a standard deviation of a shape derivative on the implicit surface; and providing the three dimensional shape of the modeled object for use in manufacturing a physical structure corresponding to the modeled object using one or more computer-controlled manufacturing systems.

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using generative design processes. A method includes obtaining a design space for a modeled object, one or more design criteria for the modeled object, and one or more in-use load cases; iteratively modifying a generatively designed three dimensional shape of the modeled object in the design space in accordance with the one or more design criteria and the one or more in-use load cases for the physical structure, comprising: performing numerical simulation of the modeled object in accordance the one or more in-use load cases, computing shape change velocities for an implicit surface in a level-set representation of the three dimensional shape, changing the shape change velocities in accordance with a polynomial function, and updating the level-set representation using the shape change velocities to produce an updated version of the three dimensional shape.

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using generative design processes. A method includes obtaining a design space for a modeled object, one or more design criteria, one or more in-use load cases, and one or more specifications of material, wherein the design criteria comprise a required number of loading cycles for the modeled object; iteratively modifying a generatively designed three dimensional shape of the modeled object, comprising: performing numerical simulation of the modeled object, finding a maximized stress or strain element for each of the one or more in-use load cases, determining an expected number of loading cycles for each of the one or more in-use load cases, redefining a fatigue safety factor inequality constraint for the modeled object, computing shape change velocities in accordance with at least the fatigue safety factor inequality constraint, and updating the level-set representation.

Generative design shape optimization with damage prevention over loading cycles for computer aided design and manufacturing

Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for suggesting products from available parts. A plurality of available parts in an inventory is identified, including identifying at least one assembly of plural individual parts or sub-assemblies. For each assembly, plural sub-assemblies or individual parts included in a respective assembly are determined. An inventory list is created that includes the plurality of available parts, the at least one assembly, and the determined sub-assemblies or individual parts of an assembly. An inventory of products is identified that constitute assemblies. Each product in the inventory of products has a respective parts list identifying parts required to build the product. The inventory list is evaluated including comparing the inventory list to the inventory of products to locate candidate products constructible using the elements included in the inventory list. Product suggestions are output.

Methods, systems, and apparatus, including medium-encoded computer program products, for designing three dimensional lattice structures include, in one aspect, a method including: obtaining a lattice within a 3D lattice design space for a 3D model being created with a 3D modeling program; identifying junctions in the lattice that are potential sources of particle traps at an interface between the 3D lattice design space and a surface present in the 3D model; and removing the potential sources of particle traps by modifying cell space defined between the identified junctions and the surface. In addition, the surface can be a surface of a solid region defined in the 3D model, and the method can include: identifying beams in the lattice having junctions lying on the surface; and extending each of the identified beams by a length amount to cause overlap between the identified beams and the solid region.
