Abstract: A method for designing a mechanism including rigid bodies and mechanical joints including obtaining input parameter values which represent the mechanism in an input state. The method also includes determining output parameter values which represent the mechanism in an output state. The determining includes minimizing an objective function under constraints. The objective function penalizes a distance between the output dimensional values and the input dimensional values. The constraints include a first constraint representing verification of the closure equation by the output parameter values. The constraints further include a second constraint representing mobility of the mechanism in the output state. This forms an improved solution for designing a mechanism comprising rigid bodies and mechanical joints.

Abstract: Embodiments perform automatic slot propagation in CAD models. One such embodiment identifies a first instance of a tab feature in a CAD model. The first instance of the tab feature is associated with a corresponding first instance of a slot feature. Next, a second instance of the tab feature in the CAD model is identified, e.g., a tab that does not have a slot. In turn, the slot feature is automatically propagated by creating a second instance of the slot feature in a component of the CAD model. The second instance of the slot feature corresponds to the identified second instance of the tab feature. In this way, embodiments automatically create slots for tabs without slots.

Abstract: Embodiments are directed to functionality for automatically trimming structural members in computer-aided design (CAD) models. An embodiment obtains a CAD model that includes a joint where a first structural member and a second structural member meet at an extremity of at least one of the first structural member and the second structural member. In turn, trimming is automatically applied to the joint using one or more processor executed rules. The one or more rules indicate the applied trimming based upon (i) geometry of the first structural member, (ii) geometry of the second structural member, and (iii) location of the joint where the first structural member and the second structural member meet.

Abstract: A method configures a housing for an assembly via a simulation of the assembly and housing in a computer assisted drafting environment. The assembly includes compartments for components and at least one opening between two neighboring compartments. Based on received parameters, aspects of the assembly and the housing are defined, bounding volumes are created for each housing compartment, and bridgings between compartments are defined. A base shell volume of the housing is calculated using Boolean operations on the bounding volumes, and a topological volume is calculated from the base shell volume. A housing assembly model is determined based on the topological volume.

Abstract: A pseudo micro computed tomography (CT-like) image of a porous material is produced. A chemistry-based 3D structure of a porous material system is generated, and a Connolly surface for the 3D structure is determined. A volume field of the 3D chemistry-based structure is calculated from the Connolly surface. A text-format file layer having layer by layer information of the volume field is generated. The text-format layer file is converted into a CT-like binary image file in the RAW format. The binary image file is converted to a black and white or grayscale images. A pore size analysis (PSA) simulation is performed to produce grain images and pore images for the porous material system.

Abstract: A computer-implemented method for selecting materials of components of a product to be manufactured. The method includes obtaining a set of materials for the components of the product. The method also includes obtaining, for each component, a set of use and/or manufacturing and/or material constraints for the component. The method also includes obtaining, for the product, a set of use and/or manufacturing constraints for the product. The method also includes obtaining, for the product, one or more material compatibility constraints. The method also includes obtaining specifications. The specifications indicate an extent of compatibility of one or more reference materials within the set of materials with the constraints. The method also includes determining, for each component of the product, at least one optimal material, with respect to compatibility with the constraints and based on the provided specifications, for manufacturing the component.

Abstract: Techniques for simulating fluid flow using a lattice Boltzmann (LB) approach for solving scalar transport equations and solving for total energy are described. In addition to the lattice Boltzmann functions for fluid flow the techniques include modifying a set of state vectors of the particles by adding specific total energy to states of particles that will be advected and subtracting the specific total energy from states of particles that will not be advected over a time interval and performing advection of the particles according to the modified set of states.

Abstract: Embodiments assess vehicle noise. One such embodiment defines a computer-based model of a vehicle and automatically determines aerodynamic performance and propulsion performance of the vehicle based on the defined computer-based model. Responsively, a flight-dynamics simulation of the vehicle is performed using the determined aerodynamic performance and propulsion performance. Performing the flight-dynamics simulation produces flight status data. The flight status data is automatically down-sampled to generate a reduced dataset. A high-fidelity flow simulation of the vehicle is performed using the reduced dataset. Performing the high-fidelity flow simulation determines in-flight aerodynamic and aeroacoustic performance of the vehicle. In turn, based on the determined in-flight aerodynamic and aeroacoustic performance, noise physical characteristics of the vehicle are determined and an indication of the determined noise physical characteristics is stored in computer memory.
