Dependent Parameter

About this Block

What it does: A Dependent Parameter defines a relationship between variables by calculating its value from other parameters (commonly Independent and/or Constant Parameters, but can also form chains with additional Dependent Parameters) using a custom function. In a parameter optimization study, a dependent parameter is typically used to define the optimization objective and constraints. Other available parameters include the Independent Parameter, and Constant Parameter Common uses:

• Inverse Design Optimization using Parameter Optimization
• Defining a design variable that is a complex mathematical expression of other variables.
• Linking multiple input parameters together through a single parameter to maintain a specific relationship between them.

Tips:

• The easiest way to create a Dependent Parameter is by right clicking on a block that defines the function you want to use as part of your optimization, and then selecting Optimize > Create Dependent Parameter.
• You can connect dependent parameters to create a Chained Dependent Parameter by linking multiple dependent parameters.
