Export the optimized model

1. In the Simulation Navigator, expand the solution node→Results.

2. Double-click the Structural node.

3. In the Post Processing Navigator, right-click the Structural node and choose Material Density Results.

4. To work with a design cycle other than the last one, from the Result list, select the desired design cycle.

5. To change the minimum material density value for the solid elements, in the Solid Area subgroup, move the Lower Bound slider to the left or right.Alternatively, you can type the appropriate value in the box and then press Tab. The range is from 0.0 to 1.0.As you reduce the lower boundary, more solid elements appear in the optimization results. As you increase it, more solid elements are removed.

6. To change the color of all of the elements with a material density value equal to or greater than the defined lower boundary, click Color and then specify the color to use in the Color dialog box.

7. If your solution includes a lattice structure, in the Lattice Area subgroup, move the Lower Bound slider to the left or right to change the minimum material density value for the lattice structures.Alternatively, you can type the appropriate value in the box and then press Tab.The lower boundary for the lattice area cannot be greater than the lower boundary for the solid area. For example, if the lower boundary for the solid areas is 0.7, the lower boundary for the lattice area must be between 0.0 and 0.7.As you adjust the lower boundary for the lattice area, the lower boundary for the solid area does not change. However, the slider in the Solid Area subgroup adjusts to show that the range is between the lower boundary of the lattice area and 1.0. For example, if the lower boundary for the solid area is 0.7, and the lower boundary for the lattice area is 0.4, then the range for the slider in the Solid Area subgroup is between 0.4 and 1.0. To change that range, you must change the value for the lower boundary for the lattice area.

8. To change the color of all of the elements with a material density value less than the defined lower boundary for the solid area, click Color in the Lattice Area subgroup and then specify the color to use in the Color dialog box.

9. To better visualize the recommended design, select the Smooth (Nodal Average) check box.The smoothing process averages the material density values between the nodes and displays that portion of each element that is greater than the specified lower boundary. As a result, smoothed results with the same number of elements might appear different with a different lower boundary.

10. To dynamically update the results in the graphics window as you change the display settings, select the Automatic Display Update check box.If you clear that check box, you must click Update Display in order to reflect your changes in the graphics window.Tip: For large or complex models, disabling automatic updates might improve performance.

11. To further smooth any 3D tetrahedral elements based on their proximity to one another, from the Additional Smoothing list, select Laplacian Smoothing.To set a factor that determines the number of times to run the smoothing algorithm, move the Smoothing Level slider to the right or left, or type the appropriate value in the box and then press Tab. The range is from 0.00 to 1.00.Higher values produce greater smoothing, but also shrink the model.Note: Changes to the Laplacian smoothing level are not visible in the graphics window. To visualize the effect of any changes, you must export the model and then import it in the Modeling or Pre/Post application.

12. To export data about the model, select one or more of the following check boxes and then click Export:Facets in STL Format—Exports the element free faces of the model as an STL file that you can import into the Modeling application.Facets in Nastran BDF Format—Exports the element free faces of the model as a Nastran BDF file that you can import into the Pre/Post application.Density CSV—Appears when the Smooth (Nodal Average) check box is cleared. Creates a comma-separated values (CSV) file that indicates the material density value for each element in your model.This file also includes the lattice structure type and the lower boundary for the material density values for the solid and lattice areas.
