Abstract: A computer-implemented method for use in analyzing a model of a repetitive structure includes generating a plurality of blocks based on the model such that the blocks are arranged end to end. The method also includes defining at least one boundary condition on an inlet of the model and on an outlet of the model, generating a plurality of constraints to be applied to the blocks to define connectivity between adjacent blocks, defining an inlet state based on the boundary condition and at least a portion of the constraints. The method further includes detecting when a first block passes a trigger plane at the inlet of the model, erasing a state of a second block at the outlet of the model, shuffling the second block to an inlet zone, and resetting the state of the second block to the inlet state.

Abstract: An embodiment of the invention involves increasing the penalty stiffness within a finite element simulation increment, which is more accurate because it avoids following a solution path with significant non-physical penetrations. An embodiment of the present invention begins by determining a first value of a parameter used by a finite element simulation of a load increment. Next, a first solution of the finite element simulation is determined by performing Newton iterations using the first value of the parameter until a first convergence check is satisfied. Then, a second value the parameter is determined wherein the second value of the parameter is unequal to the first value of the parameter. Finally, a second solution of the finite element simulation is determined by continuing the Newton iterations using the second value of the parameter until a second convergence check is satisfied, the first convergence check being different than the second convergence check.

Abstract: A computer-implemented method and corresponding system perform generative design of an energy storage device. The method automatically builds at least one model of the energy storage device. The building is based on a design parameter space and employs a machine learning process. The method automatically performs a simulation of the energy storage device using the design parameter space, a design evaluation space, and the at least one model built. The performing produces at least one prediction. The method automatically evolves at least one of (i) the design parameter space and (ii) the design evaluation space. In an event the at least one prediction indicates that a product design objective or model design objective has been achieved, the method automatically converges on the design parameter space evolved, thereby completing a generative design of the energy storage device and, otherwise, repeats the building, performing, and evolving.

Abstract: A computer-implemented method and corresponding computer-based system generate a three-dimensional (3D) multi-scale model of a 3D system. The computer-implemented method generates, at a given scale, an artifact model that indicates properties, characteristics, and artifacts of the 3D system. The computer-implemented method modifies a series of representational models of the 3D system based on the artifact model generated. Modifying the series includes mapping the properties, characteristics, and artifacts to a representational model in the series of representational models at a higher scale or lower scale relative to the given scale. The mapping bridges a given representational model of the series of representational models at the given scale and the representational model at the higher scale or lower scale. The computer-implemented method automatically stores, in a database, the artifact model in association with the series of representational models modified, thereby generating the 3D multi-scale model of the 3D system.

Abstract: Embodiments are directed to methods and systems for automatically determining a resource layout. An example embodiment begins by obtaining data indicating a position and a task performed by each resource of a plurality of resources. Then, for each resource of the plurality, a respective zone on a plane of interest occupied by the resource is automatically determined using the obtained data indicating the position and the task performed by the resource. In turn, determined zones of two or more resources of the plurality of resources are automatically combined into a combined zone based upon criteria and a file, e.g., a CAD/CAM file, indicating a layout of the plurality of resources on the plane of interest is automatically created based upon the determined zones and the combined zone.

Abstract: The invention is directed to a method for navigating in a product structure of a product, the product comprising a set of three-dimensional modeled objects. The method comprises: (a) displaying a three-dimensional graphical representation of the product; (b) selecting a three-dimensional modeled object of the product; and (c) displaying a graphical representation of a number of levels of a hierarchy of the product structure of the product. The number of levels is determined according to levels identified in a simple path in the hierarchy of the product structure between the selected three-dimensional modeled object and a highest level of the hierarchy. The method selects a level among levels identified in the simple path in the hierarchy of the product structure of the product; and finds, in the set of three-dimensional modeled objects, a second set of three-dimensional modeled objects according to the selected level of the hierarchy. Display of the found second set of three-dimensional modeled objects is then emphasized in the screen view (i.e., user interface).
