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.
- 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.
- From the Maxwell 2D/3D menu, select Optimetrics
Analysis > Add
Statistical
.
The Setup Statistical Analysis dialog box appears. - Under the Calculations tab, type the maximum number of iterations you want Maxwell to perform in the Maximum Iterations text box.
- If you want to specify an initial seed value, select the Specify initial seed value check box and enter a positive value in the text box. Each different seed value creates a new statistical sequence.
- Specify a solution quantity to evaluate.
- In the Calculation text box, set the value at which the solution quantity is to be computed.
- Optionally, modify the distribution criteria to be used.
- 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.
- Set HPC and Analysis Options, which allows you to select or create an analysis configuration.
- If you want to save the field solution data for the design variations solved during analysis, select Save Fields.
