Assign Material

The default material used for Mechanical is structural. We need to change it to the new material we defined earlier (TissueBone). In the outline window, right click on Model, and select Refresh Materials. Then, expand Geometry and highlight Solid Body 1. The bone model will now be highlighted in green, meaning it is being selected. Right below the outline window you will see "Details of Solid Body 1". Expand Material, and change the assignment to Bone. The material properties we defined for Bone will now be assigned to the bone model.

Right click on Named Selections and insert a new named selection. Change the Scoping Method to Worksheet.

...

In the main window you will see an empty table. Right click on the empty table and click on Add Row.

We will now enter the appropriate information that will help us create a named selection that includes all the faces in the top edge of the model viewed from the XY plane.

...

Click on Generate to generate the named selection. Rename it top y.

We will repeat the same steps to create a named selection for all the faces on the bottom edge of the model viewed from the XY plane.

...

The y coordinate for the bottom edge is 3.3e-2 mmm. Rename the second named selection bottom y
