Tree

The tree shows information about your model in a hierarchical tree format.

Tree nodes can be expanded by selecting  and collapsed by selecting .

When you select a node in the tree that can be interacted with, the properties panel updates to show the properties of that node.

The tree’s title changes depending on which tab is selected. You have the following options:

Model

With Model selected in the title tab, the tree shows information about your model’s geometry. By default, the tree shows the Assembly. To view Bodies, select the right hand-side button at the bottom of the tree .

In the Assembly view, each part of a CAD file is listed beneath the CAD file, and each face of a part is listed beneath the part.

On desktops and laptops, hover over a part or face in the tree to highlight it in the 3D viewer.

You can select multiple parts or multiple faces. To clear your selection, click or tap the empty space around the model in the 3D viewer.

To assign a material to one or more selected parts, use the Material field in the properties panel.

In the Bodies view, each body is listed and each part of a body is listed beneath the body.

On desktops and laptops, hover over a body in the tree to highlight it in the 3D viewer.

To assign a material to one or more selected parts, use the Material field in the properties panel.

Renaming, hiding, isolating, suppressing, adding/removing from a body

You can hide, isolate, suppress and add/remove CAD parts to/from a body.

The following table describes what each operation does. See Part icons and Right-click context menu for information on how to perform these operations.

Action Description
Rename Rename part, face, body or CAD file.
Hide
Hide the part or body in the 3D viewer. This can help you to focus on other areas in your model.
This does not remove the part or body from your model and it will still be considered when you run a simulation study.
Isolate
Hide all other parts in the 3D viewer and show only this one.
Once you’ve isolated a CAD part, you enter isolation mode. You can then choose to show additional parts by isolating them also. To exit isolation mode, either select EXIT ISOLATION MODE or hide all parts.
Suppress
Hide the part or body and remove it from your model. It will not be considered when you run a simulation study.
If you have already applied physics constraints and/or parameters to the part or body, these will be ignored in the run.
 If you later decide to unsuppress the part or body, it will automatically be added to the model again along with any associated physics constraints and/or parameters.
Add to Body
Add the part to a body. You can choose to add the part to a new body by selecting Create Body or you can choose to add the part to a pre-existing body by selecting the body name. If you have chosen to create a new body you will enter body creation mode where you can choose the properties of the new body and add additional parts to it. Once you have selected all parts to add to the body, select Done to create the body.
Remove from Body
Remove the part from a body or bodies. You can choose to remove the part from all bodies or you can remove the part from a specific body by selecting the body name.
Remove
Remove the body. The body will be deleted from the model.

Part icons

Icon Description
Part is visible. Select to hide it.
Part is hidden. Select to show it ( ) or, if in isolation mode, to isolate it ( ).
Part is isolated. Select to hide the part or, if this is the only isolated part, to exit isolation mode.

Where a part has been suppressed, its name is shown struck through.

Right-click context menu

Action Description
Rename Rename the part, face, body or CAD file.
Hide > Hide Hide a visible part or body.
Hide > Show Show a hidden part or body.
Hide > Isolate Isolate the part.
Suppress Suppress the part or body.
Add to Body > Create Body Add the part to new body.
Add to Body > Body Name Add the part to pre-existing body by name.
Remove from Body > Remove from all Bodies Remove the part from all bodies.
Remove from Body > Body Name Remove the part from body by name.
Remove Remove body.

Physics

With Physics selected in the title tab, the tree shows information about physics constraints that have been applied to the model.

You add physics constraints or loads using the toolbar.

Each constraint or load is listed under the appropriate Physics type, and the faces to which it has been applied are listed under it.

 

To edit or remove a constraint or load, select it in the tree (or in the 3D viewer). The properties panel updates to show the properties of the constraint/load. Select to edit these properties or to delete the constraint/load.

Right-click context menu

Action Description
Edit Physics Edit the physics constraint/load properties (in the properties panel).
Rename Rename the physics constraint/load.
Remove Remove the physics constraint/load.

Simulator

With Simulator selected in the title tab, the tree shows information about any simulation studies that have been run for this design version. It also includes a Current Study node which includes a dropdown of mesh, sensor and parameter information for the current study. When Current Study is selected, the launcher is active allowing you to run the current study.

 

When you select Global Mesh in the dropdown, information about that mesh is shown in the properties panel. From there you refine/coarsen the mesh and see advanced mesh settings.

When you select Global Sensor in the dropdown, the output sensor for the current study is shown in the properties panel. This can be edited by selecting .

When you select a parameter name in the dropdown, the parameter properties is shown in the properties panel. This includes the component of your model to which the parameter applies and the parameter values. These can be edited using (Edit icon).

To add a parameter to your model, select when setting the value of the property in the properties panel.

You can also view the results of a completed study by selecting in the tree (shown on hover on desktops and laptops and on selection of the simulation study on tablets).

You can run multiple simulation studies at once. You don’t have to wait for a simulation study to finish before running another one.

Right-click context menu

Action Description
Edit Sensor Edit the sensor.
Edit Parameter Edit the parameter.
Rename Rename the parameter, sensor or simulation study.
Remove Remove the parameter or sensor.

Materials

With Simulations selected in the title tab, the tree shows materials that you’ve added to your model. Click a material to show the material properties in the properties panel.

 

To add a material to your model, select a part in the model tree or in the 3D viewer and then use the Material dropdown in the properties panel to assign a material to the part.
