Controlling the Display of Simulation Entities

Controlling which simulation entities are displayed and how they are

displayed is useful for managing the appearance of a Pro/ENGINEER

Mechanica simulation model.

constraints, without having to turn on the display of datumcoordinate systems.

o Load/Constraint Display: Options in this area enable you to control thedisplay of items related to loads and constraints. The options here controlthe display of each item as a whole as opposed to by type as is the caseon the Loads / Constraints tab. Specific items include the display of

names and values, as well as the scale and density of the icons displayedon the model.

o AutoGEM Control Display: Options in this area can be used to turn thedisplay of AutoGEM controls as a whole on or off (that is, icons, names,and values), or it can be used to turn AutoGEM names and AutoGEMvalues on and off independent of each other and the their icons.

Modeling Entities: This tab can be used to control the display of specific types ofidealizations and connections. For instance, you can use this tab to turn off thedisplay of spring and mass idealizations along with weld connections, whileleaving shell idealizations and rigid link connections turned on.

Loads / Constraints: This tab can be used to turn the display of specific types ofloads and constraints on and off by their type. For instance, you could turn offthe display of all pressure loads and displacement constraints, while leavingforce/moment loads and symmetry constraints displayed.

Set Visibilities: This tab can be used to turn the display of entire load sets andconstraint sets on and off. It is analogous to adding load sets and constraintsets to a layer and then hiding or showing the layer.

Mesh: This tab is used to manage the display of mesh elements. The display ofspecific mesh entities (such as beams, solids, and shells) can be turned on andoff. The display quality (fine, medium, or coarse) of the mesh elements can becontrolled on this tab as well. Another particularly useful option in this tab is the

Shrink Elements option. This option is extremely useful for visualizing the mesh,particularly inside the model.

Overriding Default Load and Constraint Colors

When you are creating a load or constraint, you can override the default color of the

load or constraint by clicking the Edit Color icon. This opens the Pro/ENGINEERcolor editor window, enabling you to change the color of the entities associated withthe load or constraint.

Moving Tags

To make models easier to view it is possible to move the name and value tagsassociated with a load or constraint to a new location. This is done by selecting the

load or constraint, right-clicking and selecting Move Tag. You can then click a new

location where you want to move the tag. The tag will move to that location and a

leader will connect to the reference it was originally attached to.

Procedure: Controlling the Display of Simulation Entities

ScenarioControl the display of simulation entities.

DisplayControl eng_block_rear.prt

Task 1. Start the Mechanica application. Move and change the color of the existingconstraint tags.

1. Click Applications > Mechanica.

2. Select the Bolt constraint as shown. Right-click and select Move Tag.

3. Click approximately where shown in the figure to move the tag to a new location.

Note that in place of 6 individual tags, there now is a single tag in the new

location with leader lines connecting to the references for the constraint.

4. Click Named View List and select 3D_BACK.

5. Select the Surface_Thrust constraint as shown. Right-click and select Move Tag.

6. Click approximately where shown in the figure to move the tag to a new location.

7. Click Named View List and select Standard Orientation.

8. If necessary, select the Surface_Thrust constraint again. Right-click and select Edit

Definition.

9. Click Edit Color from the Constraint dialog box.

10. Type 255 in the R field, 127 in the G field and 0 in the B field to create an orange

color. When the dialog box appears as shown, click Close > OK.

Task 2. Modify some of the simulation display settings.

1. Click Simulation Display from the main toolbar.

2. If necessary, select the Settings tab.

3. Select the Display Current Csys Triad check box.

4. Select the Modeling Entities tab and clear the Material Assignments check box.

5. Select the Loads / Constraints tab and clear the Force/Moment Loads checkbox.

6. Click OK to close the Simulation Display dialog box.

Task 3. Mesh the model and modify the display settings of the mesh.

1. Click Create from the main toolbar. Click Create in the AutoGEM dialog box tomesh the model.

Note that the mesh process will take about 3060 seconds to complete.

2. When the mesh is complete, click Close in the Diagnostics dialog box to close it.

3. Click Simulation Display from the main toolbar.

4. Select the Mesh tab and clear the Mesh Points check box.

5. Select the Shrink Elements check box and type 30 in the percentage field asshown.

6. Click OK to close the Simulation Display dialog box and view the changes.

Note how shrinking the elements enables you to better see the mesh

elements that make up the structure, especially those on the internal

portions of the model.

7. Click Close from the AutoGEM Summary dialog box, followed by Close from theAutoGEM dialog box. When you are prompted to save the mesh, click No.

8. Return to the Standard Pro/ENGINEER mode by clicking Applications > Standard.


9/9

9. Click Save from the main toolbar and click OK to save the model.

10. Click File > Erase > Current > Yes to erase the model from memory.

This completes the procedure.
