Displaying post-processing results with CAD geometry or pre-processing data

Many times, you will find it useful to display CAD geometry or pre-processing data (such as polygon geometry or boundary conditions) with the post-processed results in a single post view. For example, to:

• Superimpose results from a fluid volume mesh on the underlying CAD geometry that makes up the negative space.

• Show a contour plot on a component part model in the context of its parent assembly.

• Display load and constraint symbols along with results.

Understanding layers in post-processing

By default, when you create a post view, all other layers in the model are set to Invisible. This ensures a clean display showing only the selected results data. When you click Return to Model , the results display is removed and all other layers are returned to their previous state.

For more information about layers, see Layer Settings.

You can use the Gateway command Menu→Format→Layer Visible in View to restore visibility to layers and combine pre- and post-processing data in a single post view.

For more information about the Layer Visible in View command, see Layer Visible in View.

General technique for combining displays

You can display results on geometry or pre-processing data in a post view using the following technique:

1. In the Post Processing Navigator, load your results. You can use results associated with any loaded Simulation file, or, if you are displaying results on unrelated CAD geometry, you can import the appropriate results set.

2. In the Simulation Navigator or the Simulation File View, right-click the part you want to display and choose Make Displayed Part. Display the master model to show results on the original CAD geometry.Display the idealized part to show results on idealized geometry.Display the FEM file to combine results displays with meshes or polygon geometry.Display the Simulation file to combine results displays with loads, constraints, or simulation objects, as well as meshes and polygon geometry.

3. Use the Show and Hide commands or the visibility check boxes in the Simulation Navigator to display only those entities you want to include in the post view.

4. Switch to the Post Processing Navigator.

5. Create and edit a post view. Use the visibility controls under the post view node in the Post Processing Navigator to display only those meshes or groups you want to include in the post view. See Controlling the visibility of results.

6. Choose Menu→Format→Layer Visible in View. Click OK.

7. In the Layer Visible in View dialog box, select all layers and click Visible. Click OK.Your current pre-preprocessing display is now visible in the post view.

With the post view displayed, you can now continue to work in both the Post Processing Navigator and the Simulation Navigator to refine your display.

Note that if you create a new post view, any layers visible in the current view are again set to Invisible.
