CAD Model Error Detection via Analytical-Physical Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structural analysis software often requires iterative and time-consuming processes to detect and rectify errors between analytical and physical elements in CAD models, leading to frustrating and lengthy analysis cycles due to inaccuracies in analytical representations.
Innovation Solution
A system and method that automatically detect errors between analytical and physical elements in CAD models by comparing their properties and locations, notifying users of potential issues such as support distance errors, circular references, and instabilities, allowing for real-time correction before structural analysis.

Engineering Contradiction Analysis
1Reliability
If users manually export and analyze analytical representations in structural analysis software, then structural analysis can be performed, but the process becomes time-consuming and iterative due to error detection delays
Solution Approach 1:
The system performs preliminary error detection by comparing analytical elements with physical elements in the CAD model before structural analysis is executed. This advance checking identifies mismatches, missing elements, and inconsistencies in the analytical representation, allowing users to correct errors before they cause analysis failures, thus eliminating iterative re-analysis cycles.
Solution Approach 2:
The system provides automated feedback by continuously monitoring and comparing analytical representations with physical models during the design process. When errors or inconsistencies are detected, the system notifies users immediately, enabling real-time correction rather than waiting for analysis execution to reveal problems.
2Measurement precision
If analytical representations are simplified to reduce analytical noise, then analysis results become cleaner, but errors in the analytical representation may go undetected
Solution Approach 1:
The comparison system provides continuous feedback between simplified analytical representations and detailed physical models, ensuring that simplifications do not introduce errors. By automatically detecting mismatches even in simplified models, the system maintains validity while allowing necessary simplifications for clean analysis results.
3Adaptability or versatility
If users manipulate analytical representations to capture eccentricities, then structural behavior can be better represented, but errors such as excessive element displacement may occur
Solution Approach 1:
The system performs preliminary validation of analytical element positions against physical model geometry before analysis. When users manipulate analytical elements to capture eccentricities or special structural behaviors, the comparison system checks whether displacements exceed reasonable thresholds or create geometric inconsistencies, alerting users to potential errors before analysis execution.

AI summary
Methods and apparatus, including computer program products, for identifying an analytical representation of a plurality of physical elements in a computer aided design (CAD) model, the analytical representation comprising a plurality of analytical elements. one or more of the plurality of analytical elements corresponds to one or more of the plurality physical elements. An association is identified between corresponding analytical and physical elements such that a modification to one element can be applied to modify a corresponding other. An error is automatically detected in the analytical representation.
