Engineering Contradiction Analysis
1Reliability
If manual processes are used for setting simulation conditions, then simulation accuracy can be maintained through expert judgment, but the process becomes time-consuming and limits accessibility to experts only
Solution Approach 1:
The system enables automatic setting of simulation conditions by analyzing CAD model morphology and applying predefined rules, allowing the system to serve itself without requiring expert manual intervention. The morphology analysis engine automatically identifies features and sets appropriate simulation conditions based on geometric characteristics.
Solution Approach 2:
The patent replaces the manual expert judgment process with an automated computational system that uses morphology analysis and rule-based algorithms to determine simulation conditions, substituting human mechanical processes with automated computational methods.
2Adaptability or versatility
If manual expert judgment is used for setting simulation conditions, then complex simulation scenarios can be accurately configured, but the complexity and time required for the process increases
Solution Approach 1:
The system segments the complex simulation setup process into distinct automated stages: morphology analysis of the CAD model, identification of specific geometric features, application of predefined rules for each feature type, and automatic generation of simulation conditions. This segmentation simplifies the overall complex process.
Solution Approach 2:
The system automatically adjusts simulation parameters and conditions based on the analyzed morphology and identified features of the CAD model, dynamically changing parameters to match the specific characteristics of each simulation scenario without requiring manual configuration.
3Productivity
If automated methods are introduced for setting simulation conditions, then productivity and speed are improved, but the system requires advanced morphology analysis and rule-based processing capabilities
Solution Approach 1:
The system performs preliminary morphology analysis and feature identification automatically before the simulation setup phase, preparing the necessary information in advance. This preliminary action enables rapid automated configuration without requiring complex processing during the actual simulation setup.
Solution Approach 2:
The patent introduces a morphology analysis engine as an intermediary component that bridges the CAD model and the simulation setup process. This intermediary automatically extracts geometric features and translates them into appropriate simulation conditions, simplifying the overall system architecture.

AI summary
Unlike existing methods that rely on a manual procedure for setting conditions for performing computer-based simulations, embodiments automatically set conditions for a simulation of a real-world object represented by a computer aided design (CAD) model. In one such embodiment, the morphology of a CAD mode is analyzed to identify a function of an element of the CAD model. In turn, conditions for a simulation are defined based upon one or more rules corresponding to the identified function of the element of the CAD model, where said defining includes automatically setting conditions in a simulation of the real-world physical object.
