Constants are fixed factors. A constant will be used in the workflow - but not the design analysis.
In Synthace, this specifically relates to the Mixture Composition parameter in both the Make Mixtures and Mix Onto elements.
In this tutorial you will learn:
Where to add a mixture component Constant.
How to define the levels of the Constant you want to define.
Defining a constant
Build a workflow that defines a set of liquids and provides those liquids to a Make Mixtures element.
Switch the workflow builder into DOE Mode.
Note: only the elements that can have DOE factors applied to their parameters will be interactive and display in colour.
Select the Make Mixtures element and toggle on the Mixture Compositions parameter to identify that you intend to describe these mixtures with DOE factors.
Click the adjacent factor button in the Instance Panel to launch the DOE Factor Panel.
Click on the “ADD” button to select a factor type.
Select the “New Constant” Option to open the Factor Definition Panel.
Defining factor properties
In the Factor Definition Panel, click on the Factor Name entry field enter the name of the Constant. In this example Liquid A.
Select the units for this factor.
Note: the units for your factor must match the units you set for your stock liquid component within your workflow.
Input the level you wish to use for your Constant.
Click on “Add Factor” to save the factor to your Factor Table where you will see a summary of the factors settings.
Well done on making it to the end of this tutorial.
