# Orthotropic Material

## About this Block

**What it does:** Defines an orthotropic material using a list of provided orthotropic material properties. Orthotropic materials have mechanical or thermal properties in two or three planes perpendicular to each other. Wood is an example of an orthotropic material.

**Common uses:**

* Simulation or analysis of an orthotropic material.

**Tips:**

* Acceptable inputs include both physical and thermal properties.
* Most required inputs are separated into their X, Y, and Z components.

***

Defines an Orthotropic Material by providing a list of Orthotropic Material Properties. The properties of an orthotropic material can vary in three mutually orthogonal directions.
