To Perform a Feasibility Study
 |
You cannot specify an integer parameter to be used in the optimization or feasibility study.
|
1. Click Analysis and then click the arrow next to 
Feasibility/Optimization. Click Feasibility/Optimization. The Optimization/Feasibility dialog box opens.
Feasibility/Optimization. Click Feasibility/Optimization. The Optimization/Feasibility dialog box opens.2. Under Study Type/Name, select Feasibility.
3. Accept the default name or type the name for the study.
4. To create a design constraint, click Add under Design Constraints. The Design Constraint dialog box opens.
a. Select an analysis feature parameter and an operator (=, <, or >=).
b. Under Value, click Current to accept the current value or click Set to type the value for the constraint.
c. Click OK in the Design Constraints dialog box to return to the Optimization/Feasibility dialog box.
The names and values for the selected constraints appear under the headings Parameter, Operator, and Value. You can edit these entries directly by clicking on the cell.
5. To delete a design constraint, select a constraint and click Delete.
6. To set a design variable, choose one of these buttons under Design Variables:
◦ Add Dimension—Select a dimension to vary. Enter its minimum and maximum values. You can add several variable dimensions.
◦ Add Parameter—From the Parameter Selection dialog box, select an existing independent model parameter and enter its minimum and maximum values.
7. To edit an entry, click the cell and enter a new value.
8. To delete a design variable, select a variable and click Delete.
9. Optionally, you can set preferences for the study by choosing > . In the Graphs tab, you can set the following options:
◦ Goal—Show in a graph convergence between the selected goal parameter and the chosen constraints after the computation is made.
◦ Constraints—Show in a graph constraint parameter values during the computation.
◦ Variables—Show in a graph variable values during the computation.
In the Run tab, you can set the following options:
◦ Convergence %—Use the default or type in a value for the convergence criterion. Computation stops when the difference between the parameter values for the current and previous iteration is less than the Convergence %. The lower the value, the longer the calculation takes and, if there is a feasible solution, the more accurate the results are.
◦ Max Iterations—Use the default or type in a value for the maximum number of iterations for the computation. The higher the value, the longer the calculation takes and the more specific the results are.
◦ Animate model—Animate changes in the model for the computed results.
10. Click OK to save and accept the changes for the Preferences dialog box.
11. Click Compute. Creo Parametric calculates and displays the results.
12. To create an Optimization feature, click > and type a name for the feature.
| | Make Feature option is available only when you compute the analysis. |
13. To save the study, click > .
14. Click Close to close the dialog box.
