When preparing geometry for numerical simulations, it is often required to mark individual surfaces in the model. These surfaces can then be used, for example, as an inlet or for applying forces and pressures in a structural simulation.<\/p>\n\n\n\n

The STEP format supports named entities. The question is: how to set the names in the CAD program? And how to achieve that they are actually stored in the STEP file? In the following, these questions are answered for the software PTC Creo.<\/p>\n\n\n\n

Name Surfaces<\/h3>\n\n\n\n

Select \u201cFile\u201d > \u201cPrepare\u201d and then \u201cOpen Model Properties\u201d, then select \u201cNames\u201d in the model properties dialog:<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n
\"\"<\/a><\/figure>\n\n\n\n

You can then select faces by clicking on them and enter a name in the dialog box:<\/p>\n\n\n\n

Exporting Names in STEP File<\/h3>\n\n\n\n

If you export an STP file with the default settings, the names will not be stored in the file. You need to change the export setup for them to be kept.<\/p>\n\n\n\n

Open the settings dialog via \u201cFile\u201d > \u201cOptions\u201d. Then navigate to \u201cConfiguration Editor\u201d. Here, you need to add the option \u201cintf_out_assign_names\u201d and set it to \u201cuser_name\u201d.<\/p>\n\n\n\n

Accessing Named Entities in ISCAD<\/h3>\n\n\n\n

It is now possible to access faces through their assigned names, e.g., in ISCAD. Once the STEP file is imported, its sub-entities can be explored by typing Ctrl-I (see below). The named faces appear as \u201cface_\u201d in the hierarchy:<\/p>\n\n\n\n
