Response Surface Results Design of Experiments Result

When more than one variable is included in the setup, the Response Surface view is available. You can choose any two variables as the X, Y axis and choose an output calculation as the Z axis, by clicking the “...” button next to the View list. From the Response Surface tab of the Design of Experiments Post Analysis Display dialog box, the View list lets you select all available views of the selected response-surface-setup.

Response surfaces are functions of varying natures in which the output parameters are described in terms of the input parameters. Built from the Design of Experiments (DOE), they quickly provide the approximated values of the output parameters throughout the design space without having to perform a complete solution. The accuracy of a response surface depends on several factors: the complexity of the variations of the solution, the number of points in the original DOE, and the response surface type. Once a response surface has been generated, you can create and manage response points and charts. These postprocessing tools help you to understand how each output parameter is driven by input parameters and how you can modify your design to improve its performance.

Clicking the ellipsis button [...] by the View for Response Surface opens a dialog that lets you adjust the variables selected and the values applied.

Tuning a Response Surface

For the X Axis and Y Axis, you can specify a Resolution, and the variable to use. For the Z Axis, you can select the Cost or calculation. For variables not selected for the X and Y axis, a slider is enabled that lets you adjust the value to see the effect on the response surface plot. You can enable or disable Real time mode by using the check box at the lower left.

Full Range Axis

When the Full Range Axis option is checked, all Axes are set to their maximum ranges, and the ranges won’t be changed while tuning unless you change the axis variable.

When it is unchecked, the Y(2D)/Z(3D) axis range is auto updated to fit the curve/surface.

Accumulate Response Curve

It always be unchecked when the tuning dialog started and won’t restore it last check/uncheck state. When it is checked, it will retaining the existing curves, and add new curve to the plot. Unchecking the checkbox won’t clear the accumulated curves, just stop to accumulate new curve. When the Axis variable is changed, all accumulated curves will be cleared.

Exporting Response Surface Data
