## About this Block

**What it does:** The **Constant Parameter** block creates a parameter with a fixed value. It is used to define a constant design variable that does not change during optimization. Other available parameters include the **Independent Parameter** and **Dependent Parameter**.

**Common uses:**

* Inverse Design Optimization using Parameter Optimization
* Defining fixed design variables in an optimization problem.
* Specifying unchanging material properties, boundary conditions, or dimensional constraints.

**Tips:**

* Use meaningful label names to easily identify constants in optimization results.
