Optimetrics
Optimetrics enables you to determine the best design variation among a model's possible variations. You create the original model, the nominal design, and then define the design parameters that vary, which can be nearly any design parameter assigned a numeric value in HFSS. For example, you can parameterize the model geometry or material properties. You can then perform the following types of analyses on your nominal HFSS design:

Parametric |
In a parametric analysis, you define one or more variable sweep definitions, each specifying a series of variable values within a range. For example, you can parameterize component values. (See Variables in HFSS for more information.) Optimetrics solves the design at each variation. You can then compare the results to determine how each design variation affects the performance of the design. Parametric analyses are often used as precursors to optimization solutions because they help to determine a reasonable range of variable values for the optimization analysis. |
Optimization |
For an optimization analysis, you identify the cost function and the optimization goal. Optimetrics changes the design parameter values to meet that goal. The cost function can be based on any solution quantity that HFSS can compute. |
Sensitivity |
In a sensitivity analysis, you use Optimetrics to explore the vicinity of the design point to determine the sensitivity of the design to small changes in variables. |
Tuning |
Tuning allows you to change variable values interactively while monitoring the performance of the design. If you want to ensure that tuning does not resolve variations already solved by parametric setup, you must check Save Fields Mesh in the Options tab of the optimetrics setup. |
Statistical |
In a statistical analysis, you use Optimetrics to determine the distribution of a design's performance, which is caused by a statistical distribution of variable values. |
Note |
Sweeping or using a complex variable is not allowed in any optimetrics setup, including optimization, statistical, sensitivity, and tuning setups. |
You can also Link to ANSYS Design Xplorer. This permits you to manage an HFSS Optimetrics simulation from the ANSYS Workbench.
