How to create a Mechanical region?

To create a Mechanical region, click the Mechanical regions node of the Data tree:

Figure 1. The New Mechanical region dialog box.


Then, in the New Mechanical region dialog box:

  • Provide a name for the Mechanical region;
  • Select the type of the Mechanical region in the drop-down menu. Two region types are available:
    • Material region and
    • Air region (only useful in the context of free-shape optimization).
  • In the case of a Material region, also provide the following Mechanical properties of the region:
    • the Young modulus (MPa),
    • the Poisson ratio and
    • its Mass density (kg/m3).
  • Finally, inform the geometrical faces that integrate the Mechanical region in the List of application faces.
