Solution Overview
Problem
Existing design simulation workflows require manual intervention for initiating and viewing results, disrupting the design process by taking users away from their core activity of creating and refining product designs.
Innovation Solution

1Productivity
If manual simulation invocation is used, then simulation accuracy is maintained, but design productivity deteriorates due to discrete steps taking users away from core design activities
Solution Approach 1:
The patent merges the simulation functionality with the CAD system by integrating the simulation engine directly into the CAD application. This allows users to perform both design modeling and simulation analysis within a single unified environment, eliminating the need to switch between separate applications and thereby improving design productivity while maintaining ease of operation.
Solution Approach 2:
The system automatically detects design changes and triggers simulation execution without requiring manual user initiation. This preliminary automatic action ensures that simulations are run at appropriate moments based on actual design modifications, reducing the burden on users to manually manage simulation workflows while maintaining accurate timing for simulation execution.
2Productivity
If automatic simulation execution is implemented, then design efficiency improves by eliminating manual re-runs, but system complexity increases due to automated trigger detection and result management
Solution Approach 1:
The system implements self-service automation where the CAD system automatically monitors its own design model for changes, detects trigger events, initiates simulation execution, and manages result presentation without external intervention. This self-service approach improves design efficiency by eliminating manual re-runs while containing system complexity within automated routines that operate transparently in the background.
Solution Approach 2:
The system establishes a feedback loop where simulation results are automatically presented to users and can trigger further design modifications. This closed-loop feedback mechanism improves design efficiency by providing immediate results that guide subsequent design iterations, while the feedback management is handled through structured automated processes that manage system complexity.
3Measurement precision
If simulations are automatically re-run based on CAD modifications, then measurement precision of design validation is improved, but loss of time occurs due to computational processing requirements
Solution Approach 1:
The system employs periodic action by automatically executing simulations at regular intervals triggered by design changes rather than continuously monitoring every possible modification. This periodic execution strategy maintains measurement precision of design validation by running simulations when actually needed, while reducing loss of time by avoiding unnecessary continuous computation and allowing the system to operate efficiently between trigger events.

AI summary
A method of executing a simulation model while generating an associated structural model includes changing, by a computer-aided design (CAD) system, the structural model. The method further includes evaluating, by the CAD system, at least one trigger criterion to determine if the change to the structural model is a simulation trigger event. The method also includes executing, by the CAD system, the simulation model if the change to the structural model is determined to be the simulation trigger event.
