  • Patent number: 10867087
    Abstract: Systems and methods for performing power analytics on a microgrid. In an embodiment, predicted data is generated for the microgrid utilizing a virtual system model of the microgrid, which comprises a virtual representation of a topology of the microgrid. Real-time data is received via a portal from at least one external data source. If the difference between the real-time data and the predicted data exceeds a threshold, a calibration and synchronization operation is initiated to update the virtual system model in real-time. Power analytics may be performed on the virtual system model to generate analytical data, which can be returned via the portal.

  • Patent number: 10853539
    Abstract: A robotic assembly cell is configured to generate a physical mesh of physical polygons based on a simulated mesh of simulated triangles. A control application configured to operate the assembly cell selects a simulated polygon in the simulated mesh and then causes a positioning robot in the cell to obtain a physical polygon that is similar to the simulated polygon. The positioning robot positions the polygon on the physical mesh, and a welding robot in the cell then welds the polygon to the mesh. The control application captures data that reflects how the physical polygon is actually positioned on the physical mesh, and then updates the simulated mesh to be geometrically consistent with the physical mesh. In doing so, the control application may execute a multi-objective solver to generate an updated simulated mesh that meets specific design criteria.

  • Patent number: 10846445
    Abstract: An example modeling process of pore pressure and injected waste distribution profile may include several steps. A hydrodynamic flow simulation model may be built according to the geometry and/or physical properties of the subsurface formation. A fluid distribution and pore pressure profile in the subsurface may be affected by the geometry and orientation of hydraulic fractures created as a result of drill cuttings subsurface injection (cuttings re-injection or CRI). A fracture profile may be generated using a hydraulic fracturing simulation and may then be embedded into the hydrodynamic simulation model. In some examples, the nature of injected fluids in the same formation and through the same well, fracture, and/or perforation interval may lead to modification of the subsurface formation properties, and this may be accounted for in the simulation.

  • Patent number: 10846442
    Abstract: Methods provide computationally efficient techniques for designing gauge patterns for calibrating a model for use in a simulation process. More specifically, the present invention relates to methods of designing gauge patterns that achieve complete coverage of parameter variations with minimum number of gauges and corresponding measurements in the calibration of a lithographic process utilized to image a target design having a plurality of features. According to some aspects, a method according to the invention includes transforming the space of model parametric space (based on CD sensitivity or Delta TCCs), then iteratively identifying the direction that is most orthogonal to existing gauges' CD sensitivities in this new space, and determining most sensitive line width/pitch combination with optimal assist feature placement which leads to most sensitive CD changes along that direction in model parametric space.

  • Patent number: 10810332
    Abstract: A method is provided for simulating communication between a client system and application entity via an application interface, thereby enabling integration testing with a simulation apparatus. Data is transmitted from the simulation apparatus to the application entity via the application interface, and the simulation apparatus records outputs along with contexts and respective latencies. The client system transmits requests to the simulation apparatus which returns simulated responses based on the stored outputs having similar contexts, and with artificial latencies replicating the previously recorded latencies. Other events generated in the application entity may also be recorded and simulated accordingly. Reporting and analytical data may be provided to identify potential performance issues and other errors prior to direct integration of the client system and application interface.

  • Patent number: 10783289
    Abstract: Embodiments of the invention provide systems and methods for nesting objects in 2D sheets and 3D volumes. In one embodiment, a nesting application simplifies the shapes of parts and performs a rigid body simulation of the parts dropping into a 2D sheet or 3D volume. In the rigid body simulation, parts begin from random initial positions on one or more sides and drop under the force of gravity into the 2D sheet or 3D volume until coming into contact with another part, a boundary, or the origin of the gravity. The parts may be dropped according to a particular order, such as alternating large and small parts. Further, the simulation may be translation- and/or position-only, meaning the parts do not rotate and/or do not have momentum, respectively. Tighter packing may be achieved by incorporating user inputs and simulating jittering of the parts using random forces.

  • Patent number: 10762255
    Abstract: A reduced order model of an integrally bladed turbine disk (IBD) is used with experimental vibrational test data to modify a finite element model (FEM) of the IBD so that the FEM more accurately predicts the vibrational mistuning of the disk. The refined FEM can be used to evaluate a proposed modification of the IBD before the hardware is actually modified, and to evaluate the actual modification if there is a difference between the proposed and actual modifications.

  • Patent number: 10747921
    Abstract: A method for simulating operation of a system. The method accesses information characterizes system behavior, identifies system components and characterizes component behavior and relationships. The components include composite or non-composite unit types. A user selects an instance root and the method induces an instance hierarchy from that root. The instance hierarchy is displayed on a GUI in the form of a navigable tree or breadcrumbs view. Operation of the system is simulated using the instance hierarchy. Embodiments further include the concepts of merging certain variable names, displaying producing and consuming downstream and upstream elements, positioning, rotating, or orienting diagram elements to avoid overlapping with other diagram elements, identifying statically constant variables and propagating constness to producer and consumer variables, storing simulation results in compressed form and decompressing as needed, and identifying differences between dataflow diagrams.
