1Measurement precision
If physics computation methodology is used to simulate complex multi-component physics behaviors, then accuracy of simulation is improved, but computational resources and time consumption increase significantly
Solution Approach 1:
The simulation domain is segmented into multiple components, each represented by calibrated models. This segmentation allows the complex system to be divided into manageable parts that can be simulated efficiently using pre-calibrated relationships rather than full physics computations for each component.
Solution Approach 2:
Calibrated models are prepared in advance through calibration processes that establish relationships between input and output variables. This preliminary action eliminates the need for detailed physics computations during actual simulation, as the calibrated models directly provide component behaviors based on input variables.
2Reliability
If detailed physics-based computations are performed for each component, then simulation fidelity is improved, but setup complexity and time consumption increase
Solution Approach 1:
Component behaviors are calibrated in advance by establishing relationships between input and output variables. This preliminary calibration eliminates the need for detailed physics-based setup during simulation preparation, significantly reducing setup time while maintaining fidelity through the calibrated relationships.
Solution Approach 2:
Instead of performing detailed physics computations for each component, the system uses calibrated models that copy the essential input-output behavior of components. This copying approach maintains simulation fidelity while eliminating complex setup procedures.
3Productivity
If calibrated models are used to represent components, then computational efficiency is improved, but integration with physics computations requires additional interface management
Solution Approach 1:
An interface mechanism is introduced that mediates between calibrated models and physics computations. This intermediary handles the exchange of information between the two approaches, managing the integration complexity while allowing both methods to work together efficiently in the simulation system.
