1. The Purpose of SpaceClaim Parametrization
(1) Rapid Design Changes and Iteration
- One-click modification: Adjust parameter values to automatically update the entire model without manual redrawing or step-by-step feature modifications.
- Efficiency improvement: Especially suitable for product series, such as brackets and enclosures with different specifications.
(2) Optimization Analysis Integration
- Seamless integration with ANSYS Workbench: Parameters can be directly passed to ANSYS Workbench for parametric simulation, automatically running simulations for different dimensional schemes (such as the effect of thickness and length on strength).
- DOE (Design of Experiments) implementation: Batch exploration of design space, combined with optimization algorithms to automatically find the optimal dimensional combination.
2. Parametrization Method
In the ANSYS Workbench platform, drag in a Geometry module, open a geometry model, and enter SpaceClaim.
Here we want to parameterize two key dimensional parameters. Select the Pull function from the toolbar.
Select the outer circle of the model, and the radius value of the outer circle will be displayed, while a P will appear next to the radius, as shown below.
Click the P icon next to the radius to complete the parameterization of the outer circle radius. At this time, the P icon will change to a D icon, indicating that the parameterization is complete.
Then select the inner hole of the model, and the radius value of the inner hole will be displayed. Similarly, click the P icon next to it to complete the parameterization.
After the parameterization is complete, the P icon will also change to a D icon. At this point, the parameterization of both key dimensions is complete.
At the same time, you can see the parameterized dimensions in the parameter list on the left side of the Workbench platform.
Double-click the parameter name to modify the parameter value, and the model will update automatically.
3. Parameter Optimization Example
After the parameterization is complete, you can perform parameter optimization in ANSYS Workbench. The following is a simple example of parameter optimization.
In the parameter optimization interface, you can set the range of parameter changes and optimization goals. The system will automatically run multiple simulations to find the optimal parameter combination.
4. Summary
Through SpaceClaim’s parametrization function, CAE engineers can quickly achieve model modification and optimization analysis. This method not only improves work efficiency but also provides strong support for product design optimization. Mastering this technique will bring significant convenience to your CAE work.
