The Assign Materials dialog box lists the assembly and components in hierarchical order. Each component can use either the originally assigned material, or you can override the material selection with another from the Material Library list provided. Material overrides are applied per simulation, thus one component can have several material assignments each in a different simulation within the same assembly document.
If appropriate, you can work with multiple component material rows simultaneously (See Work with multiple component materials under Prepare for Analysis.)

Assign
Alternatively, you can double-click the parent Material browser node or right-click the node and select Assign Materials. |
To define a new material or modify an existing one, see Add a New Material or Edit Materials.
When assigning an override material to a component with more than one instance in the assembly, all instances update to reflect that material. Material overrides are listed in two places in the simulation browser. In the Materials folder, they display by material. The components using that material display as child nodes.
When you assign material overrides, the dialog box presents the following information and options:
| Component | Hierarchical list of components in the assembly. All instances of components are displayed. | |
| Original Material | The material currently assigned to a specific component. | |
| Override Material | The material you assign to analyze a different material. | |
| Safety Factor |
Specifies whether to use Yield Strength or Ultimate Tensile Strength when determining the Safety Factor. The default setting is Yield Strength. The setting affects the component material for that simulation. For ductile materials, select Yield Strength. For brittle materials, select Ultimate Tensile Strength. |

Edit Material Overrides
There are two ways to edit material overrides:
| Delete Materials | Removes the material override. The command is accessed only through the context menu of either the material or component nodes. Right-click the material node and click Delete Materials.
|
| Remove Redundant Overrides | Inspects the overrides of component nodes and deletes redundant material overrides. The command is available in the context menus for the Material node and all child nodes. |
Modify Material Properties
When you add or modify materials for use with simulation, define the following properties carefully:
- Young’s modulus must be greater than zero.
- Density and Yield Strength must be greater than zero.
- Poisson’s ratio must be between 0 and 0.5, but not equal to 0.5.
Promote Materials
| Promote materials to model |
Accessed from the component browser node context menu, this command promotes the override material into the component file. The component file is edited and the material is changed to the promoted material. The override cell updates to display As Defined. Other simulations using the override are not updated. Use the Remove Redundant Overrides command to update each simulation. For each component whose material is promoted, that component is removed from the Material browser folders. When no materials exist in a node, the node is removed. Note: With Show All Materials active, the component is not removed from the Material browser folder. Only the icon is changed to reflect that the material is no longer an override.
