The COMSOL Selections Window
In the PTC Creo Parametric™ user interface, click the Selections button on the COMSOL Multiphysics tab to open the COMSOL Selections window where you can set up user-defined selections of geometric entities to be synchronized with the COMSOL® model.
Alternatively, to create a user-defined selection right-click a feature or component in the PTC Creo Parametric™ model tree, and choose COMSOL Selections. This also opens the COMSOL Selections window, and adds the new selection to the list of Selections. You can add additional items to the selection by selecting on the geometry or in the tree.
The Selections list contains the list of user-defined selections for the active file in PTC Creo Parametric™. For each selection from the list you can review and modify the entities included in the selection. These appear in the Entities list. You can also edit the selection name, which is displayed in the Selection name field.
The following is a list of geometric entities or model elements that can be selected on a PTC Creo Parametric™ design:
•
solid or surface bodies
•
components that can be parts, or subassemblies of an assembly
•
features
•
entities, such as faces, edges, and points
If you are using PTC Creo Parametric™ together with the Windchill® PLM software, only the selection of assembly components is supported when synchronizing assemblies that have not been checked out.
To create a new selection click the New () button. A selection can only contain entities of the same type, for example, only faces or only points. The first item added to a selection determines the type for the selection. Change the selection mode in PTC Creo Parametric™ to select different entity types, and use the model tree to select assembly components, features and solid bodies. The toggle buttons above the Selections list filter which selections are displayed based on their type. To remove a selection from the Selections list right-click the selection, then select Delete. Selecting Clear deletes all selections from the list.
To remove an item from a selection right-click the item in the Entities list, then select Delete.
To turn off the synchronization of the material selections clear the Generate selections from materials checkbox. After the next synchronization the selections based on materials will not appear in the COMSOL model.
Selections are automatically saved in the PTC Creo Parametric™ file the next time you save the file. To reload the selections saved in the PTC Creo Parametric™ file click the Revert to Saved button.
To confirm changes and close the COMSOL Selections window click OK. This step is necessary before synchronizing between PTC Creo Parametric™ and COMSOL to transfer the selections.
