  • Publication number: 20210004512
    Abstract: A system includes a meshing module, one or more physics solvers, one or more sensitivity computation modules, and one or more optimizer modules. The meshing module generates a mesh of a design domain corresponding to an object to be manufactured. The physics solvers each generate physical field variables and objective values based on the mesh and boundary conditions specified on solid-void boundaries of the design domain. The sensitivity computation modules compute a sensitivity field based on the mesh and the physical field variables. The optimizer modules generate an updated design comprising new design variables by executing an optimization of the design domain based on the sensitivity field and the objective values. The physics solvers, the sensitivity computation modules, and the optimizer modules are iteratively executed until convergence to generate a final design based on the new design variables generated by the optimizer modules.

  • Patent number: 10534875
    Abstract: A method of partitioning a model to facilitate printing of the model on a 3D printer includes identifying partition sensitive locations on the model and creating a binary tree with a root note representative of the model. An iterative partitioning process is applied to divide the model into objects by selecting a node of the binary tree without any children nodes, identifying a portion of the model corresponding to the node, and determining candidate cutting planes on the portion of the model based on the partition sensitive locations. During the process, analytic hierarchical processing (AHP) is applied to select an optimal cutting plane from the candidate cutting planes based on partitioning criteria. The optimal cutting plane is used to segment the portion of the model into sub-portions, and two children nodes representative of these sub-portions are created on the node of the binary tree.

  • Publication number: 20190026410
    Abstract: A method for providing adaptive resilience to a system defined by physical components includes generating an ontology comprising objects. Each object corresponds to (i) functions performed by a discrete physical component of the system; (ii) behaviors of the discrete physical component; (iii) physical structures included in the discrete physical component; and (iv) events that impact usage of the discrete physical component. Relationships are added to the ontology for each physical component including aggregation relationships, composition relationships, and dependencies between the physical components. Sensor data is received from sensors monitoring the physical components. Based on the data, an event is identified that is impacting physical components performing a system function. The ontology's attributes and relationships are used to generate an alternate system design comprising physical components that are functionally equivalent to the impacted components with respect to the system function.
