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 computer-implemented method is disclosed for creating three-dimensional (3D) variable resolution (VR) region geometries of a modeled object for use in a computer-implemented numerical simulation involving the modeled object. The computer-implemented method includes, inter alia, generating two-dimensional (2D) orthographic views of a 3D modeled object, and identifying edges of each of the 2D orthographic views with a computer-based ray casting method. The computer-based ray casting method includes, for each respective one of the 2D orthographic views, casting virtual rays from different directions toward the 2D orthographic view within a plane of the 2D orthograph view, and detecting an intersection point for each of the virtual rays with an edge of the 2D orthographic view.

Abstract: A computer-implemented method and corresponding computer-based system perform a computer simulation, via at least one processor, of a filling stage of an injection molding process that fills a part cavity of a part with material over a filling time. The simulation is based on a boundary integration method and a mesh model. The mesh model represents the part cavity. The simulation computes a part thickness distribution of the part based on the mesh model. The boundary integration method computes velocity and temperature at a flow front of the material over the part thickness distribution computed and determines advancement of the flow front based on the velocity and temperature computed. The simulation outputs, via the processor, at least one indication of behavior of the injection molding process determined based on the simulation. The simulation transpires in real-time relative to the filling time.

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.
