05.Set the Body Attributes and the Material Properties

We assign names to the body attributes and the material properties. Various parameters associated with them will be set up here, too.

The body attribute is required to be set on each body. Various specific data, such as the thickness in the 2D analysis, the width of the wire element, the coordinates for anisotropic material, can be set on the body attribute.

Body attribute is distinguished by its name. Therefore it is not allowed to assign the same name to the different body attributes.
 

Material property constitutes the body. The material data might vary depending on the simulation you try.

Material property is distinguished by its name. Therefore it is not allowed to assign the same name to the different material data.

 

Procedure

  1. Assign a name to the substrate.

    Highlight the substrate on the modeling window and click to select.
     

  2. To select a particular body out of several overlapping bodies, try the following methods:
     

    • Space Key Method

      Rest the mouse pointer on the overlapping area, and press the <Space> key.
      Body selection will change. The left-click will fix the selection.
       

    • List Selection Method

      Rest the mouse pointer on the overlapping area, and press the <Tab> key.
      The body selection list will appear. Select the body of your interest and left-click to fix the selection.


      For more information, see How to Select Bodies and Topologies where you will find [Clicking the Mouse] and [List Selection Method].
