Abstract: A computer-based method is disclosed of creating a visual representation of a threaded feature on a three-dimensional (3D) modelled object in a computer-aided design environment. The method includes constructing a helical curve and start and end circles for a threaded feature in a 3D modelled object, trimming the helical curve to conform to a geometry of the modelled object, identifying a boundary of the trimmed helical curve; and displaying a cosmetic thread to visually represent the threaded feature based on the trimmed helical curve and the identified boundaries of the trimmed helical curve.

Abstract: A 3D modeled CAD object is flattened to a two dimensional 2D representation while maintaining a user selected wiring component represented in 3D. A user selected 3D component has a connector and a route segment with at least one stored sketch segment. A 3D and 2D tangent are calculated at a junction point of the route segment. A translation and rotation transformation is calculated to align the 2D and 3D tangents at the junction point. A calculated transformation matrix based on the translation and rotation transformation is used to display a flattened unconnected route segment aligned with the user selected 3D component.

Abstract: Disclosed are techniques for simulating a physical process and for determining boundary conditions for a specific energy dissipation rate of a k-Omega turbulence fluid flow model of a fluid flow, by computing from a cell center distance and fluid flow variables a value of the specific energy dissipation rate for a turbulent flow that is valid for a viscous layer, buffer layer, and logarithmic region of a boundary defined in the simulation space. The value is determined by applying a buffer layer correction factor as a first boundary condition for the energy dissipation rate and by applying a viscous sublayer correction factor as a second boundary condition for the energy dissipation rate.

Abstract: A three dimensional (3D) backshell component is flattened to a two dimensional (2D) representation while maintaining a connected wiring component in 3D. Sketch segments for a curved 3D backshell connected first route segment within the backshell housing are stored. A first tangent is computed for a first entry point at a first end point of the connected first route segment, and a flattened route is calculated for route segments unconnected to the backshell. A flattened route position and a second tangent are calculated for a second route segment connected with the first route segment at a second entry point corresponding to the first entry point. The first entry point and the second entry point are aligned, and the first tangent and the second tangent are aligned, and the flattened unconnected route segment aligned with the 3D backshell component is displayed.

Abstract: Computer implemented techniques for simulating a fluid flow about a surface of a solid are disclosed. These techniques involve receiving a model of a simulation space including a lattice structure represented as a collection of voxels and a representation of a physical object, with the voxels having appropriate resolutions to account for surfaces of the physical object. The techniques also involve simulating movement of particles in a volume of fluid, with the movement of the particles causing collisions among the particles, identifying faces between two voxels where at least one of the faces violates a stability condition, computing a modified flux using a spatially averaged gradient in the vicinity of the two voxels where the at least one of the faces violates the stability condition, and performing by the computing system, advection operations on the particles to subsequent voxels.

Abstract: A computer-implemented method for 3D printing planning including obtaining a set of spare parts to be manufactured in one or more factories comprising 3D printers and other manufacturing machines. The method further including obtaining 3D printing constraints. The constraints include one or more constraints each representing a 3D printing constraint and/or a mechanical constraint for a spare part. The constraints further include one or more 3D printing capacity constraints for the one or more factories. The method further includes obtaining a reference set of one or more spare parts each classified either as compatible with the constraints or as non-compatible with the constraints. The method further includes determining an optimal subset of the set of spare parts to be 3D printed. The determining includes optimizing one or more objective manufacturing functions under the constraints and based on the reference set.

Abstract: A computer-implemented method for CAD volume extrusion operator detection in a CAD 3D model representing a mechanical part. The method includes obtaining a segmentation of the CAD 3D model. The CAD 3D model includes a skin representing an outer surface of the mechanical part. The segmentation comprises segments each representing a skin portion. The method further includes iteratively grouping segments. Segments of a pair are grouped when: each segment of the pair is an extrusion surface and a union of the segments is an extrusion surface having a same extrusion axis as the segments, or each segment of the pair is an extrusion surface and one of the two segments is a closing plane for the other segment. The method further includes determining one or more CAD volume extrusion operators, each corresponding to a respective group.
