  • Publication number: 20240135064
    Abstract: A method for maintaining a physical asset based on recommendations generated by analyzing operational data and analyzing at least one model representing the physical asset, includes constructing, by a computing device, using a port-reduced reduced basis element approximation of a partial differential equation, at least one model. The computing device analyzes an error indicator associated with the at least one model to determine that the error indicator exceeds a tolerance level and increases a number of basis functions in the port-reduced reduced basis element approximation accordingly. The computing device receives first operational data associated with a region of the physical asset and updates at least one model. The computing device provides a recommendation for maintaining the physical asset.

  • Publication number: 20230315053
    Abstract: A method for maintaining a physical asset based on recommendations generated by analyzing operational data and a composite model of a plurality of models representing the physical asset includes analyzing an error indicator associated with the composite model to determine that the error indicator exceeds a tolerance level and increases a number of basis functions in the port-reduced static condensation reduced basis element approximation accordingly. The computing device receives, from a sensor associated with the physical asset, first operational data associated with a region of the physical asset and updates the model, the operational data including data relating to a measurement of temperature and to a pressure load. The computing device determines a structural response of the physical asset to the thermal load and to the pressure load, including a determination of a level of creep strain. The computing device provides a recommendation for maintaining the physical asset.

  • Patent number: 11727162
    Abstract: A method for maintaining a physical asset based on recommendations generated by analyzing operational data and a composite model of a plurality of models representing the physical asset includes constructing, by a computing device, using a port-reduced static condensation reduced basis element approximation of at least a portion of a partial differential equation, the composite model. The computing device analyzes an error indicator associated with at least one model within the composite model to determine that the error indicator exceeds a tolerance level and increases a number of basis functions in the port-reduced static condensation reduced basis element approximation accordingly. The computing device receives first operational data associated with at least one region of the physical asset and updates the composite model. The computing device provides a recommendation for maintaining the physical asset, based upon the updated composite model.

  • Patent number: 9213788
    Abstract: Systems, methods, and apparatus for modeling and analyzing a physical system comprising a plurality of components. In some embodiments, a component type of a component of the plurality of components may be used to access a dataset from a plurality of datasets. The dataset may include a representation of at least one partial differential equation. A model of the component may be constructed based at least in part on the accessed dataset and at least one parameter relating to a physical characteristic of the component, and may be used to compute at least one output value based on at least one input value.
