LiveLink™ for PTC® Creo® Parametric™ Updates

For users of LiveLink™ for PTC® Creo® Parametric™, COMSOL Multiphysics® version 5.5 supports the synchronization of material properties applied in PTC® Creo® Parametric™. Based on the material data, Materials nodes are created in the component of the LiveLink™ feature, and their selection is set to the corresponding material in PTC® Creo® Parametric™. The synchronization of materials is enabled with a Synchronize material data check box in the Synchronize section of the LiveLink for PTC Creo Parametric node.

The geometry of a busbar assembly is shown in the Graphics window, the copper and titanium materials appear in the Materials node, and the LiveLink for PTC Creo Parametric settings are shown. Busbar assembly being synchronized via LiveLink™ for PTC® Creo® Parametric™ The TITANIUM and COPPER material nodes are generated during synchronization when the new Synchronize material data check box is selected in the settings for LiveLink™ for PTC® Creo® Parametric™.

Associative Geometry Import

The CAD file import functionality now supports associative geometry import to retain physics and other settings on the geometry after the file is reimported due to an updated design. The import reads information in the CAD files to identify the geometric entities in the file. This information is usually available when importing CAD files saved in the native format of the software where it was created.

Reimporting a modified version of this fan geometry preserves the selection of the blade faces.

Selections from Materials, Layers, and Colors

The CAD file import functionality now generates selections based on the material and layer assignments of the geometric objects, when available in the CAD file. Selections are also generated for colors assigned to geometric entities. The selections are listed in the Settings window of the Import feature.

Use material selections generated during import to easily assign materials to the imported geometry. The selections are also kept when a modified version of the geometry is reimported.

Delete Holes Defeaturing Operation

A new defeaturing operation called Delete Holes finds and deletes cylindrical holes whose radii are smaller than a given number that you can specify. After specifying a maximum radius, a Find Holes button will automatically add the appropriate holes to the selection list.

Support for New and Updated CAD File Format Versions

The CAD file export functionality now supports writing 3D geometry to the following file formats:

  • IGES (.igs, .iges): 5.3
  • STEP (.step): AP203

The CAD file import and export functionality has been extended to support new versions for the following file formats:
