Create a cross section from the face of a solid

Video: Assign a cross section to a beam face using the face of a solid

This topic describes how to create a cross section for a 1D mesh using the dimensions of a planar face of your solid geometry. If the solid geometry is later changed, the cross section will be updated automatically.

1. Edit the physical property table for the 1D mesh.

2. In the physical property table dialog box, next to Fore Section, click Show Section Manager .

3. In the Beam Section Manager dialog box, click Create Section .

4. In the Beam Section dialog box, in the Type list, choose Face of Solid.

5. In the graphics window, select a planar face to represent the cross section, as shown in the following example at .Note: In this example, the solid beam geometry is split into two separate bodies. One body has been hidden to expose a planar face to use for creating the cross section. You can also use the end face of an extruded solid, or use the Section Curve command in the Modeling application and use the resulting curves as a planar face.

6. Selection of a planar face defines the plane of the section, but not the orientation. You can define either the horizontal or vertical axis. In the Reference Vector group, from the Define Axis list, select Horizontal or Vertical.

7. Define the horizontal or vertical axis using the standard vector tools, or click Inferred and then select an edge on the solid geometry to infer the horizontal or vertical axis of the section. In the example, the horizontal axis is inferred by selecting the edge at .An arrow indicates the horizontal direction.

8. In the Beam Section dialog box, select the Preview check box to see the cross section. In this example, the horizontal direction is Z and the normal is X. The software determined the vertical direction.

9. Expand the Stress Recovery Points group. Note that default stress recovery points are provided.

10. (Optional) To add an additional stress recovery point, click Create Point .

11. In the Cross Section Preview window, select the first stress recovery point.

12. Click Done .The Y-Z coordinates for the “C” stress recovery point appear in the dialog box.

13. Repeat the above steps to define the remaining stress recovery points.

14. (Optional) Click Evaluate Section Properties to view a report of the section properties and stress recovery points. Close the Information window.

15. Click OK.
