How to Create an FE Model with Multiple Materials

Objective:

Learn how to create an FE Model that has more than one material.

Applies to:

  • Simulation
  • Topology Optimization

Procedure:

Material is applied to an FE Model by using Attributes. Each Attribute adds a new material. To add more than one material to an FE Model, you need a Region to define where that material is applied. If you only have two attributes, then one of them doesn't need a Region. Instead, that material will be applied everywhere the other material isn't. Check out the image below to see how you would set up two and three material attributes.

1. Set-Up: Download the example file and start with the FE Mesh already created.

2. FE Model:

    • Add an FE Model block. 
    • Add an FE Component
    • Input the FE Mesh variable
    • Click the + on the Attribute List to add another Attribute
    • Input a Solid Attribute into each input in the Attribute List

3. Material:

    • In the first Solid Attribute, add the Al 6061-T6 Material to the Material input.
    • Add the Stainless Steel 316 material to the second Solid Attribute
    • An error will pop up saying you need to set a Region for one of the Attributes

4. Region: 

    • Add an FE Region by Body in the second Solid Attribute
    • Set the Mesh to the FE Mesh variable
    • Set Entity to Cells
    • Set Body to the Grip Implicit Body variable

This will set the Grip part to be Stainless Steel, and set the rest of the pen body to be Aluminum.
