## About this Block

**What it does:** Assigns the Thermal Conductivity and Specific Heat to an **Orthotropic Material**.

**Common uses:**

* An input in defining an **Orthotropic Material**.
* For conducting a **Thermal Analysis**.

**Tips:**

* Create spatially varying properties by using Scalar Fields as inputs.
* Most required inputs are separated into their X, Y, and Z components.
* This block has an overload, to allow you to define an Orthotropic Nonlinear Thermal Property. This overload is in Beta.

Define an Orthotropic Nonlinear Thermal Property by specifying directional thermal properties of the desired material. Providing scalar fields as thermal properties will result in spatially varying material properties.
