Setting Up a Statistical Analysis

Following is the general procedure for setting up a statistical analysis. Once you have created a setup, you can Copy and Paste it, and then make changes to the copy, rather than redoing the whole process for minor changes. You can create a statistical setup before defining variables but all variables must be defined before you start the statistical analysis.

1. Before a variable can be included in a statistical analysis, you must specify that you intend for it to be used during a statistical analysis in the Properties dialog box.
2. Click HFSS> Optimetrics Analysis > Add Statistical , or select the Simulation tab of the ribbon and, under the Optimetrics icon, select Statistical from the drop-down menu:

   

   The Setup Statistical Analysis dialog box appears.

3. Under the Calculations tab, type the maximum number of iterations you want HFSS to perform in the Maximum Iterations text box.
4. Specify a solution quantity to evaluate.
5. In the Calculation text box, set the value at which the solution quantity is to be computed.
6. Optionally, modify the distribution criteria to be used.
7. The following optional statistical analysis setup options can also be used:
   • Modify the starting variable value.
   • Exclude variables from the statistical analysis.
   • Modify the values of fixed variables that are not being modified during the statistical analysis.
   • Request that Optimetrics solve a parametric sweep during a statistical analysis.
     Note:

     Sweeping or using a complex variable is not allowed in any optimetrics setup, including optimization, statistical, sensitivity, and tuning setups.

8. If you want to save the field solution data for the design variations solved during analysis, select Save Fields.
