Abstract: Network fabric design and analysis is generally a manual process where the wiring diagram is manually created and analyzed. Because of the complexity of modern network fabric designs, it has become increasingly more difficult to manually detect potential issues with a network fabric design. Accordingly, embodiments herein help automate the analysis of network fabric designs. In one or more embodiments, a trained neural network model or network models receive as input a wiring diagram and analyzes it. In one or more embodiments, the trained model may generate a real-valued score that represents the quality of the design. In one or more embodiments, the trained neural network may classify a particular issue or issues of the network fabric design.

Abstract: Simulation methods and systems are described for topology and shape optimization of a geometrical representation of a physical object being modeled. An initial geometry of the physical object is represented. Equation data representing physical properties for portions of an initial geometry are defined. User inputs are received through a GUI for optimization settings and user selections of portions of the geometry being optimized. For topology optimization, various material properties and solver settings may be defined. For shape optimization, various solver settings and optimization objective may be defined. A discretized model is generated of the physical object. Solutions of the topology or shape optimization are generated and updated values are determined. Iterative operations are then performed for solving the topology or shape optimization objective expressions. The solutions are stored and graphical representations of the solutions may be generated.
